TIMERS and TIMER/COUNTERS
TC1B ENABLE/DISABLE PROCEDURE
Enable Timer/Counter 1B
— Set the TC1B interrupt enable flag IET2 to logic one
— Set TMOD1B.3 to logic one
TCNT1B, IRQT2, and TOL2 are cleared to logic zero, and timer/counter operation starts.
Disable Timer/Counter 1B
— Set TMOD1B.2 to logic zero
Clock signal input to the counter register TCNT1B is halted. The current TCNT1B value is retained and can be read if
