Struct cc2650::i2s0::aifoutptrnext::W

pub struct W { /* fields omitted */ }

Value to write to the register

Methods

impl W

pub fn reset_value() -> W

Reset value of the register

pub unsafe fn bits(&mut self, bits: u32) -> &mut Self

Writes raw bits to the register

pub fn ptr(&mut self) -> _PTRW

Bits 0:31 - Pointer to the first byte in the next DMA output buffer. The read value equals the last written value until the currently used DMA output buffer is completed, and then becomes null when the last written value is transferred to the DMA controller to start on the next buffer. This event is signalized by IRQFLAGS.AIF_DMA_OUT. At startup, the value must be written once before and once after configuring the DMA buffer size in AIFDMACFG. At this time, the first two samples will be fetched from memory. The next pointer must be written to this register while the DMA function uses the previously written pointer. If not written in time, IRQFLAGS.PTR_ERR will be raised and all output pins will be disabled.
