Value
The T8 and T16 Common Functions register (CTR1) controls the functions in common
with Timer 8 and Timer 16.
Be careful to differentiate TRANSMIT mode from DEMODULATION mode, as set by
CTR1[7]. The functions of CTR1[6:0] and CTR2[6] are different depending on which
mode is selected. Do not change from one mode to another without first disabling the
counter/timers.

Description
Mode —Selects the timer mode for signal transmission or demodulation.
TRANSMIT mode.
DEMODULATION mode.
TRANSMIT Mode
P36 Out—Select normal I/O or timer output on Port 3, Pin 6.
P36 acts as normal I/O port output.
P36 acts as combined Timer 8/Timer 16 output.
DEMODULATION Mode
Demodulator Input—Select Port 2, Pin 0 or Port 3, Pin 1 as the counter/timer
input.
P31 acts as the demodulator input. If IMR[2] = 1, a P31 event can also generate
an IRQ1 interrupt. To prevent this, clear IMR[2] or select P20 as input instead.
P20 acts as the demodulator input.
