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.
