name : TIMER
description : Controls time and alarms
time is a 64 bit value indicating the time in usec since power-on
timeh is the top 32 bits of time & timel is the bottom 32 bits
to change time write to timelw before timehw
to read time read from timelr before timehr
An alarm is set by setting alarm_enable and writing to the corresponding alarm register
When an alarm is pending, the corresponding alarm_running signal will be high
An alarm can be cancelled before it has finished by clearing the alarm_enable
When an alarm fires, the corresponding alarm_irq is set and alarm_running is cleared
To clear the interrupt write a 1 to the corresponding alarm_irq

Interrupt (6) XIP_IRQ
name : XIP_SSI
description : DW_apb_ssi has the following features:
* APB interface – Allows for easy integration into a DesignWare Synthesizable Components for AMBA 2 implementation.
* APB3 and APB4 protocol support.
* Scalable APB data bus width – Supports APB data bus widths of 8, 16, and 32 bits.
* Serial-master or serial-slave operation – Enables serial communication with serial-master or serial-slave peripheral devices.
* Programmable Dual/Quad/Octal SPI support in Master Mode.
* Dual Data Rate (DDR) and Read Data Strobe (RDS) Support - Enables the DW_apb_ssi master to perform operations with the device in DDR and RDS modes when working in Dual/Quad/Octal mode of operation.
* Data Mask Support - Enables the DW_apb_ssi to selectively update the bytes in the device. This feature is applicable only in enhanced SPI modes.
* eXecute-In-Place (XIP) support - Enables the DW_apb_ssi master to behave as a memory mapped I/O and fetches the data from the device based on the APB read request. This feature is applicable only in enhanced SPI modes.
* DMA Controller Interface – Enables the DW_apb_ssi to interface to a DMA controller over the bus using a handshaking interface for transfer requests.
* Independent masking of interrupts – Master collision, transmit FIFO overflow, transmit FIFO empty, receive FIFO full, receive FIFO underflow, and receive FIFO overflow interrupts can all be masked independently.
* Multi-master contention detection – Informs the processor of multiple serial-master accesses on the serial bus.
* Bypass of meta-stability flip-flops for synchronous clocks – When the APB clock (pclk) and the DW_apb_ssi serial clock (ssi_clk) are synchronous, meta-stable flip-flops are not used when transferring control signals across these clock domains.
* Programmable delay on the sample time of the received serial data bit (rxd) enables programmable control of routing delays resulting in higher serial data-bit rates.
* Programmable features:
- Serial interface operation – Choice of Motorola SPI, Texas Instruments Synchronous Serial Protocol or National Semiconductor Microwire.
- Clock bit-rate – Dynamic control of the serial bit rate of the data transfer used in only serial-master mode of operation.
- Data Item size (4 to 32 bits) – Item size of each data transfer under the control of the programmer.
* Configured features:
- FIFO depth – 16 words deep. The FIFO width is fixed at 32 bits.
- 1 slave select output.
- Hardware slave-select – Dedicated hardware slave-select line.
- Combined interrupt line - one combined interrupt line from the DW_apb_ssi to the interrupt controller.
- Interrupt polarity – active high interrupt lines.
- Serial clock polarity – low serial-clock polarity directly after reset.
- Serial clock phase – capture on first edge of serial-clock directly after reset.
