0 should not be written to this bit.
2 IOA2 0 R/W I/O Control A2
Selects the GRA function.
0: GRA functions as an output compare register
1: GRA functions as an input capture register

R/W
I/O Control A1 and A0
When IOA2 = 0,
00: No output at compare match
01: 0 output to the FTIOA pin at GRA compare match
10: 1 output to the FTIOA pin at GRA compare match
11: Output toggles to the FTIOA pin at GRA compare
match
When IOA2 = 1,
00: Input capture to GRA at rising edge at the FTIOA
pin
01: Input capture to GRA at falling edge at the FTIOA
pin
1X: Input capture to GRA at rising and falling edges at
the FTIOA pin
[Legend]
X: Don't care.
Note: When a GR register functions as a buffer register for a paired GR register, the settings in
the IOA2 and IOB2 bits in TRDIORA and the IOC2 and IOD2 bits in TRDIORC of both
registers should be the same.
