Initial
Value R/W Description
0 R/W I/O Control D1 and D0
0 R/W When IOD2 = 0,
00: No output at compare match
01: 0 output to the FTIOD pin at GRD compare match
10: 1 output to the FTIOD pin at GRD compare match
11: Output toggles to the FTIOD pin at GRD compare
When IOD2 = 1,
00: Input capture at rising edge at the FTIOD pin
01: Input capture at falling edge at the FTIOD pin
1X: Input capture at rising and falling edges at the FTIOD

1 Reserved
This bit is always read as 1.
0 R/W I/O Control C2
Selects the GRC function.
0: GRC functions as an output compare register
1: GRC functions as an input capture register
When GRA buffer operation has been selected by
BUFEA in TMRW, select the same function as GRA.
0 R/W I/O Control C1 and C0
0 R/W When IOC2 = 0,
00: No output at compare match
01: 0 output to the FTIOC pin at GRC compare match
10: 1 output to the FTIOC pin at GRC compare match
11: Output toggles to the FTIOC pin at GRC compare
When IOC2 = 1,
00: Input capture to GRC at rising edge of the FTIOC pin
01: Input capture to GRC at falling edge of the FTIOC pin
1X: Input capture to GRC at rising and falling edges of
