I/O Control B2
Selects the GRB function.
0: GRB functions as an output compare register
1: GRB functions as an input capture register
I/O Control B1 and B0
When IOB2 = 0,
00: No output at compare match
01: 0 output to the FTIOB pin at GRB compare match
10: 1 output to the FTIOB pin at GRB compare match
11: Output toggles to the FTIOB pin at GRB compare
When IOB2 = 1,
00: Input capture at rising edge at the FTIOB pin
01: Input capture at falling edge at the FTIOB pin
1X: Input capture at rising and falling edges of the FTIOB
