address_offset : 0x10C Bytes (0x0)
size : 32 bit
access : read-write
reset_value : 0x0

CONNECTION_EVENT_LENGTH : This field defines the length of Connection event. This value is derived from the CE length HCI parameters received from the host. This determines the number of master transmit slots in a connection event, subject to either of the MD bits being set. If both MD bits are set to 0, this has no effect. Units: 625us Note: The connection event length as specified by the CE_LENGTH shall not exceed CONN_INTERVAL - 1.25 ms. The CE-length parameter, according to the Bluetooth specification, is the length of the connection event. Take an example to illustrate this scenario: Assume a connection with interval = 100ms. that the application has put allowed 20ms of CE-length. Here, the CE-length can be upto 100ms (100ms - 150us to be exact). If the connection is maintained for 5 minutes, there could be 10*60*5 = 3000 connection-intervals. The CE-length need not be maintained constant during all the 3000 connection events. Here are the typical cases that determine the value of CE-length: (1) No data packets exchanged. we are just maintaining time and frequency synchronization. In this case, only a packet pair will be exchanged every connection interval. Here, CE-length = 1. (2) Average of 10 packets to be sent per connection event. We can pump data in multiple ways here: 2.1: Send data at uniform rate : In this case, the CE-length will be enough to accommodate 10 packets, which will take about 7ms. As this is less than application enforced limit of 20ms, we can comfortably push all the 10 data packets in this connection interval. So data will be pumped to the other BT device at the same rate as is received from my application. 2.2: Can send data in bursts. Assume that we accumulate data for 1 second and pump out at the end of 1 second(this is not done by our Bluetooth stack, the application needs to buffer the data). So, at 10th connection interval, we have 100 packets accumulated. We are now ready to pump this data. 100 packets take about 70 ms. This is above the application enforced 20ms. So, the hardware can pump data that can fill up 20ms. The remaining data will be deferred to the next connection interval. So, in this case, you would see a CE-length spread over time like this (Per connection interval): 0,0,0,0,0,0,0,0,0,0, 20,20,20,10,0,0,0,0,0,0, 20,20,20,10,0,0,0,0,0,0, 20,20,20,10,0,0,0,0,0,0, and so on. (3) We are receiving data at the same rate as in (2). This case is to honor data sent by the other BT-device by giving it more time in the current connection interval. In (2) and (3) you will see non-empty packets either transmitted or received. We can also utilize the CE-length for different reasons: (4) A transaction is in progress, and we are expecting a response packet very soon. In this case, we may be exchanging only empty packets now, and in the next few packet-pairs. In this case, you will the CE-length to be large, and a non-empty packet may not be exchanged in all the slots.

All the other FIFOs are empty or hardware has cleared them after receiving acknowledgement. NOTE: The SENT status bit and ACK status bit have to be taken together to understand the meaning of packet status. The table below describes how the two bits are sequentially updated by either hardware/firmware to complete one data transmission. SENT ACK Description 0 0 Buffer is empty. No packet is queued in the buffer 1 0 Packet is queued by firmware. 1 1 Packet is transmitted by hardware. Hardware is waiting for acknowledgement. 0 1 Hardware has received ACK. Firmware has not yet processed the ACK. 0 0 Firmware has processed the ack. The buffer is again empty.

SET_CLEAR : Write: Used to set the SENT bit in hardware for the selected packet buffer. 1 - packet queued When firmware has a packet to send, firmware first loads the next available packet buffer. Then the hardware SENT bit is set by writing 1 to this bit field along with the list_index field that identified the buffer index. This indicates that a packet has been queued in the data buffer for sending. This packet is now ready to be transmitted. The SENT bit in hardware is cleared by hardware only when it has received an acknowledgement from the remote device. Firmware typically does not clear the bit. However, It only clears the bit on its own if it needs to 'flush' a packet from the buffer, without waiting to receive acknowledgement from the remote device, firmware clears BIT7 along with the list_index specified.

Read: Reads TX_ACK[3:0] If a particular bit is set, then the packet in the selected buffer has been transmitted (at least once) by the hardware and hardware is waiting for acknowledgement. Example1 : If the read value is : 0x03, then packets in FIFO-0 and FIFO-1 are acknowledged by the remote device. These acknowledgements are pending to be processed by firmware. Example2 : If the read value is : 0x02, then packet FIFO-1 is acknowledged by the remote device. This acknowledgement is pending to be processed by firmware. NOTE: The SENT status bit and ACK status bit have to be taken together to understand the meaning of packet status. The table below describes how the two bits are sequentially updated by either hardware/firmware to complete one data transmission. SENT ACK Description 0 0 Buffer is empty. No packet is queued in the buffer 1 0 Packet is queued by firmware. 1 1 Packet is transmitted by hardware. Hardware is waiting for acknowledgement. 0 1 Hardware has received ACK. Firmware has not yet processed the ACK. 0 0 Firmware has processed the ack. The buffer is again empty.
bits : 0 - 3 (4 bit)
access : read-write

SET_CLEAR : Write: Firmware uses the field to clear and ACK bit in the hardware to indicate that the acknowledgement for the transmit packet has been received and processed by firmware. Firmware clears the ACK bit in the hardware by writing in this register only after the acknowledgement is processed successfully by firmware. For clearing ack for a packet transmitted in fifo-index : '3', firm-ware will write '3' in the 'list-index' field and set this bit (BIT7) to 0. This is the indication that the corresponding packet buffer identi-fied by List-Index is cleared of previous transmission and can be re-used for another packet from now on. The ACK bit in hardware is set by hardware when it has success-fully transmitted a packet.

SET_CLEAR_C1 : Write: Used to set the SENT bit in hardware for the selected packet buffer. 1 - packet queued When firmware has a packet to send, firmware first loads the next available packet buffer. Then the hardware SENT bit is set by writing 1 to this bit field along with the list_index field that identified the buffer index. This indicates that a packet has been queued in the data buffer for sending. This packet is now ready to be transmitted. The SENT bit in hardware is cleared by hardware only when it has received an acknowledgement from the remote device. Firmware typically does not clear the bit.

Read: Reads TX_ACK[3:0] If a particular bit is set, then the packet in the selected buffer has been transmitted (at least once) by the hardware and hardware is waiting for acknowledgement. Example1 : If the read value is : 0x03, then packets in FIFO-0 and FIFO-1 are acknowledged by the remote device. These acknowledgements are pending to be processed by firmware. Example2 : If the read value is : 0x02, then packet FIFO-1 is acknowledged by the remote device. This acknowledgement is pending to be processed by firmware.

SET_CLEAR_C1 : Write: Firmware uses the field to clear and ACK bit in the hardware to indicate that the acknowledgement for the transmit packet has been received and processed by firmware. Firmware clears the ACK bit in the hardware by writing in this register only after the acknowledgement is processed successfully by firmware. For clearing ack for a packet transmitted in fifo-index : '3', firm-ware will write '3' in the 'list-index' field and set this bit (BIT7) to 0. This is the indication that the corresponding packet buffer identi-fied by List-Index is cleared of previous transmission and can be re-used for another packet from now on.
