A register associated with the interrupting channel as defined in the
CIR. Its numerical value equals
the number of bytes minus 1 (count – 1) ready for transfer to the
transmitter or transfer from the receiver. It is undefined for other
types of interrupts
10 – with receive errors
11 – w/o receive errors

A register associated with the interrupting channel as defined in the
CIR. It contains the type of interrupt code for all interrupts.
Table 34. GRxFIFO – Global RxFIFO Register
8 data bits of RxFIFO. MSBs set to 0 for 7, 6, 5 bit data
ááááááááááááááááá
The RxFIFO of the channel indicated in the CIR channel field.
Undefined when the CIR interrupt context is not a receiver interrupt.
Global TxFIFO Register

Table 35. GTxFIFO – Global TxFIFO Register
8 data bits of TxFIFO. MSBs not used for 7, 6, 5 bit data
ááááááááááááááááá
ááááááááááááááááá
The TxFIFO of the channel indicated in the CIR channel field.
Undefined when the CIR interrupt context is not a transmitter
interrupt. Writing to the GTxFIFO when the current interrupt is not a
transmitter event may result in the characters being transmitted on a
different channel than intended.

This register may be read to determine the current level of the I/O
pins and examine the output of the change detectors assigned to
each pin. If the change detection is not enabled or if the pin is
configured as an output, the associated change field will read b’0.

I/OPIOR[7:4] bits activate the input change of state detectors. If a
pin is configured as an output, a b’1 value written to a I/O field has
no effect.
I/OPIOR[3:0] bits hold the datum which is the inverse of the datum
driven to its associated I/O pin when the I/OPCR control bits for that
pin are programmed to b’01.
