CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER
8.4.3 Timer 1 Control Register (TCR1)
The timer 1 control register (TCR1) is used to select functions, allow and prohibit
operation, control interrupts, and check interrupt states in timer 1 for the 8-bit mode of
the 8/16-bit capture timer/counter. When used in the 16-bit mode, TCR1 is controlled by
the timer 0 control register (TCR0), but TCR1 setting is required.
