Appendix B: Register Details
TNFUL 11 wtc 0x0 Transmitter FIFO Nearly Full interrupt mask
status:
This event is triggered whenever a new word is
pushed into the transmit FIFO causing the fill
level to be such that there is not enough space for
a further write of the number of bytes currently
specified in the WSIZE bits in the Mode register. If
this further write were currently attempted it
would cause an overflow.
Note that when WSIZE is 00, this assumes that a
two byte write would be attempted and hence a
single byte write is still possible without overflow
by driving byte_sel low for the write.
0: no interrupt occurred
1: interrupt occurred
TTRIG 10 wtc 0x0 Transmitter FIFO Trigger interrupt mask status.
This event is triggered whenever a new word is
pushed into the transmit FIFO causing the fill
level to become equal to the value defined by
TTRIG.
0: no interrupt occurred
1: interrupt occurred
DMSI
(IXR_DMS)
9 wtc 0x0 Delta Modem Status Indicator interrupt mask
status:
This event is triggered whenever the DCTS,
DDSR, TERI, or DDCD in the modem status
register are being set.
0: no interrupt occurred
1: interrupt occurred
TIMEOUT
(IXR_TOUT)
8 wtc 0x0 Receiver Timeout Error interrupt mask status:
This event is triggered whenever the receiver
timeout counter has expired due to a long idle
condition.
0: no interrupt occurred
1: interrupt occurred
PARE
(IXR_PARITY)
7 wtc 0x0 Receiver Parity Error interrupt mask status:
This event is triggered whenever the received
parity bit does not match the expected value.
0: no interrupt occurred
1: interrupt occurred
FRAME
(IXR_FRAMING)
6 wtc 0x0 Receiver Framing Error interrupt mask status:
This event is triggered whenever the receiver fails
to detect a valid stop bit.
0: no interrupt occurred
1: interrupt occurred
