DPWM_DATA (DATA)

MODUFRQ : DPWM Modulation Frequency
bits : 0 - 2 (3 bit)
access : read-write

DEADTIME : DPWM Driver Deadtime Control Enabling this bit will insert an additional clock cycle deadtime into the switching of PMOS and NMOS driver transistors.
bits : 3 - 3 (1 bit)
access : read-write

DITHEREN : DPWM Signal Dither Control To prevent structured noise on PWM output due to DC offsets in the input signal it is possible to add random dither to the PWM signal. These bits control the dither: 0: No dither. 1: ±1 bit dither 3: ±2 bit dither
bits : 4 - 5 (2 bit)
access : read-write

DPWMEN : DPWM Enable 0: Disable DPWM, SPK pins are tristate, CIC filter is reset, FIFO pointers are reset (FIFO data is not reset). 1: Enable DPWM, SPK pins are enabled and driven, data is taken from FIFO. Note : This field will be effective only when DAC_EN field in this register is set as 0 .
bits : 6 - 6 (1 bit)
access : read-write

RXTHIE : DPWM FIFO Threshold Interrupt 0: DPWM FIFO threshold interrupt Disabled. 1: DPWM FIFO threshold interrupt Enabled.
bits : 8 - 8 (1 bit)
access : read-write

RXTH : DPWM FIFO Threshold If the valid data count of the DPWM FIFO buffer is less than or equal to RXTH setting, the RXTHF bit will set to 1, else the RXTHF bit will be cleared to 0.
bits : 9 - 12 (4 bit)
access : read-write

ZCIE : Zero Cross Enable 0: output data doesn't cross zero point 1: output data cross zero point
bits : 14 - 14 (1 bit)
access : read-write

ZOH_DIV : DPWM Zero Order Hold, Down-sampling Divisor The input sample rate of the DPWM is set by HCLK frequency and the divisor set in this register. Valid range is 1,..,255. Default is 48, which gives a sample rate of 13 kHz for a 39.936 MHz (default) HCLK.
bits : 0 - 7 (8 bit)
access : read-write

GAIN : (GAIN[7:0]+1)/256
bits : 8 - 15 (8 bit)
access : read-write

FULL : FIFO Full
bits : 0 - 0 (1 bit)
access : read-only

Enumeration:

EMPTY : FIFO Empty
bits : 1 - 1 (1 bit)
access : read-only

Enumeration:

RXTHF : DPWM FIFO Threshold Interrupt Status (Read Only)
bits : 2 - 2 (1 bit)
access : read-only

Enumeration:

FIFO_POINTER : DPWM FIFO Pointer (Read Only) The FULL bit and FIFO_POINTER[3:0] indicates the field that the valid data count within the DPWM FIFO buffer. The Maximum value shown in FIFO_POINTER is 15. When the using level of DPWM FIFO Buffer equal to 16, The FULL bit is set to 1.
bits : 3 - 6 (4 bit)
access : read-only

DMAEN : Enable DPWM DMA Interface
bits : 0 - 0 (1 bit)
access : read-write

Enumeration:

End of enumeration elements list.

INDATA : DPWM FIFO Audio Data Input A write to this register pushes data onto the DPWM FIFO and increments the write pointer. This is the address that PDMA writes audio data to.
bits : 0 - 15 (16 bit)
access : write-only
