Interrupt FIFO Level Select Register, UARTIFLS
TXIFLSEL | Transmit interrupt FIFO level select. The trigger points for the transmit interrupt are as follows: b000 = Transmit FIFO becomes <= 1 / 8 full b001 = Transmit FIFO becomes <= 1 / 4 full b010 = Transmit FIFO becomes <= 1 / 2 full b011 = Transmit FIFO becomes <= 3 / 4 full b100 = Transmit FIFO becomes <= 7 / 8 full b101-b111 = reserved. |
RXIFLSEL | Receive interrupt FIFO level select. The trigger points for the receive interrupt are as follows: b000 = Receive FIFO becomes >= 1 / 8 full b001 = Receive FIFO becomes >= 1 / 4 full b010 = Receive FIFO becomes >= 1 / 2 full b011 = Receive FIFO becomes >= 3 / 4 full b100 = Receive FIFO becomes >= 7 / 8 full b101-b111 = reserved. |
