Section 9 Timers
Timer Control Register X (TCRX)
TCRX is an 8-bit read/write register that selects the valid edges of the input capture signals,
enables buffering, and selects the FRC clock source.
TCRX is initialized to H'00 upon reset and in standby mode, watch mode, subsleep mode, and
subactive mode.
Bit 7 Input Edge Select A (IEDGA): Bit 7 selects the rising or falling edge of the input capture
A input signal (FTIA).
