13.3.8
TICRR and TICRF are 8-bit read-only registers. The contents of TCNT are transferred at the
rising edge and falling edge of the external reset input in that order, when the ICST bit in TCONRI
of the timer connection is set to 1. The ICST bit is cleared to 0 when one capture operation ends.
TICRR and TICRF are initialized to H'00. The TICRR and TICRF functions are used for timer
connection. For details, see section 14, Timer Connection.
