12.2.10 Time Constant Register C (TCORC) [TMRX Additional Function]
TCORC is an 8-bit readable/writable register. The sum of the contents of TCORC and TICR is
continually compared with the value in TCNT. When a match is detected, a compare-match C
signal is generated. Note, however, that comparison is disabled during the T2 state of a TCORC
write cycle and a TICR input capture cycle.
TCORC is initialized to H'FF by a reset and in hardware standby mode.
The TCORC function is used in timer connection. For details, see section 13, Timer Connection.
12.2.11 Input Capture Registers R and F (TICRR, TICRF) [TMRX Additional Functions]
TICRR and TICRF are 8-bit read-only registers. When the ICST bit in TCONRI is set to 1,
TICRR and TICRF capture the contents of TCNT successively on the rise and fall of the external
reset input. When one capture operation ends, the ICST bit is cleared to 0.
TICRR and TICRF are each initialized to H'00 by a reset and in hardware standby mode.
The TICRR and TICRF functions are used in timer connection. For details, see section 12.3.6,
Input Capture Operation, and section 13, Timer Connection.
