Set 0: Timer 1 clock source from internal.
Alternate Compare Bit. This bit controls whether the timer runs in single or dual
maximum count mode.
Set 1: Specify dual maximum count mode. In this mode, the timer counts to Maxcount
Set 0: Specify single maximum count mode. In this mode, the timer counts to the
Continuous Mode Bit.
Set 1: The timer runs continuously.
Timer 1 Count Value.
This register contains the current count of timer 1. The count is incremented by one
every 8 internal processor clocks, prescaled by Timer 2, or incremented by one every
8 external clocks which is configured as the external clock select bit to refer to the
TMRIN1 signal.
Timer 1 Compare A Value.
