TX-FIFO space available
0 = There is no space available in TX-FIFO.
1 = The TX-FIFO can still accept at least one data word.
RX-FIFO overrun
RX-FIFO interrupt request
TX-FIFO interrupt request
0 = There is no valid data word in RX-FIFO.
1 = There is at least one valid data word in RX-FIFO.
0 = The RX-FIFO works well.
1 = The RX-FIFO is already overrun.
Once the RX-FIFO is overrun, this bit will keep active until RX-FIFO is reset.
0 = No RX-FIFO interrupt request
1 = A RX-FIFO interrupt request is pending
0 = No TX-FIFO interrupt request
1 = A TX-FIFO interrupt request is pending
RX-FIFO overrun interrupt request
0 = No RX-FIFO overrun interrupt request
1 = A RX-FIFO overrun interrupt request is pending
Set
Reset = Valid data words in RX-FIFO drops below the threshold level.
Set
Reset = Valid data words in TX-FIFO exceeds the threshold level
Set
Reset = Reset RX-FIFO or reset device.
= Valid data words in RX-FIFO exceeds the threshold level.
= Valid data words in TX-FIFO drops below the threshold level.
= When RX-FIFO is overrun.
