FIFO trigger settings for interrupt and DMA request.
FIFOTRIG_SPEC | FIFO trigger settings for interrupt and DMA request.
|
R | Register FIFOTRIG reader
|
RXLVLENA_R | Field RXLVLENA reader - 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.
|
RXLVLENA_W | Field RXLVLENA writer - 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.
|
RXLVL_R | Field RXLVL reader - 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).

TXLVLENA_R | Field TXLVLENA reader - 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.

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).
