GRA is an output compare register:
000: Disables pin output by compare match
001: 0 output by GRA compare match
010: 1 output by GRA compare match
011: Toggle output by GRA compare match
GRA is an input capture register:
0
100: Input capture to GRA at the rising edge
101: Input capture to GRA at the falling edge
11X: Input capture to GRA at both rising and falling edges
[Legend] X: Don't care.
TIORC: TIORC selects whether GRC or GRD is used as an output compare register or an input
capture register. When an output compare register is selected, the output setting is selected. When
an input capture register is selected, an input edge of an input capture signal is selected. TIORC
also selects the function of FTIOC or FTIOD pin.
