type W = W<u32, FIFOTRIG>;

Writer for register FIFOTRIG

Methods

impl W

pub fn txlvlena(&mut self) -> TXLVLENA_W

Bit 0 - Transmit FIFO level trigger enable. This trigger will become an interrupt if enabled in FIFOINTENSET, or a DMA trigger if DMATX in FIFOCFG is set.

pub fn rxlvlena(&mut self) -> RXLVLENA_W

Bit 1 - Receive FIFO level trigger enable. This trigger will become an interrupt if enabled in FIFOINTENSET, or a DMA trigger if DMARX in FIFOCFG is set.

pub fn txlvl(&mut self) -> TXLVL_W

Bits 8:11 - Transmit FIFO level trigger point. This field is used only when TXLVLENA = 1. If enabled to do so, the FIFO level can wake up the device just enough to perform DMA, then return to the reduced power mode. See Hardware Wake-up control register. 0 = trigger when the TX FIFO becomes empty. 1 = trigger when the TX FIFO level decreases to one entry. 15 = trigger when the TX FIFO level decreases to 15 entries (is no longer full).

pub fn rxlvl(&mut self) -> RXLVL_W

Bits 16:19 - Receive FIFO level trigger point. The RX FIFO level is checked when a new piece of data is received. This field is used only when RXLVLENA = 1. If enabled to do so, the FIFO level can wake up the device just enough to perform DMA, then return to the reduced power mode. See Hardware Wake-up control register. 0 = trigger when the RX FIFO has received one entry (is no longer empty). 1 = trigger when the RX FIFO has received two entries. 15 = trigger when the RX FIFO has received 16 entries (has become full).
