Section 12 8-Bit Timer (TMR)
12.3.6
TICR is an 8-bit register. The contents of TCNT are transferred to TICR at the rising edge of the
external reset input. TICR cannot be directly accessed by the CPU. The TICR function is used for
the timer connection. For details, refer to section 13, Timer Connection.
12.3.7
TCORC is an 8-bit readable/writable register. The sum of contents of TCORC and TICR is always
compared with TCNT. When a match is detected, a compare-match C signal is generated.
However, comparison at the T2 state in the write cycle to TCORC and at the input capture cycle of
TICR is disabled. TCORC is initialized to H'FF. The TCORC function is used for the timer
connection. For details, refer to section 13, Timer Connection.
12.3.8
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, refer to section 13, Timer Connection.
12.3.9
TISR selects a signal source of external clock/reset input for the counter.

Input Select
Selects an internal synchronization signal (IVG signal) or
timer clock/reset input pin VSYNCI/TMIY (TMCIY/TMRIY)
as the signal source of external clock/reset input for the
TMR_Y counter.
0: IVG signal is selected
1: VSYNCI/TMIY (TMCIY/TMRIY) is selected
