Struct lpc55_pac::usart0::fifotrig::R

pub struct R(_);

Register FIFOTRIG reader

Implementations

impl R

pub fn txlvlena(&self) -> TXLVLENA_R

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(&self) -> RXLVLENA_R

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(&self) -> TXLVL_R

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(&self) -> RXLVL_R

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).

Methods from Deref<Target = R<FIFOTRIG_SPEC>>

pub fn bits(&self) -> REG::Ux
