Timer 8/Timer 16 Control Register
The Timer 8/Timer 16 Counter/Timer register allows the start time of the T8 and T16
counters to be synchronized by simultaneously programming bits 7 and 6 to ‘1’. It also can
freeze the T16 output value and change T8 DEMODULATION mode to capture one cycle
of a carrier.
