Section 12 8-Bit Timers
12.2.12 Timer Input Select Register (TISR) [TMRY Additional Function]
TISR is an 8-bit readable/writable register that selects the external clock/reset signal source for the
counter.
TISR is initialized to H'FE by a reset and in hardware standby mode.
Bits 7 to 1—Reserved: Do not write 0 to these bits.
Bit 0—Input Select (IS): Selects the internal synchronization signal (IVG signal) or the timer
clock/reset input pin (VSYNCI/TMIY (TMCIY/TMRIY)) as the external clock/reset signal source
for the counter.
