[7] Interrupt is generated for TxFIFO starve ERROR.
This occurs whenever the TxFIFO is read when it is still
empty. This is considered an ERROR and will have
unexpected results
1: IRQ source enabled
0: IRQ source disabled
[6] Interrupt is generated for TxFIFO overflow ERROR.
This occurs whenever the TxFIFO is written when it is already
full. This is considered an ERROR and will have unexpected
results
1: IRQ source enabled
0: IRQ source disabled
[5] Interrupt is generated whenever the RxFIFO is empty
1: IRQ source enabled
0: IRQ source disabled
[4] Interrupt is generated whenever the RxFIFO is
ALMOST_EMPTY which is defined as RX_FIFO_DEPTH <
RX_FIFO_DIPSTICK
1: IRQ source enabled
0: IRQ source disabled
[3] Interrupt is generated whenever the RxFIFO is full
1: IRQ source enabled
0: IRQ source disabled
[2] Interrupt is generated whenever the RxFIFO is
ALMOST_FULL which is defined as RX_FIFO_DEPTH > (32
– RX_FIFO_DIPSTICK)
1: IRQ source enabled
0: IRQ source disabled
[1] Interrupt is generated for RxFIFO starve ERROR.
This occurs whenever the RxFIFO is read when it is still
