COMPARE Mode
When the timer is disabled, the Timer Output signal is set to the value of this bit. When the
timer is enabled, the Timer Output signal is complemented upon timer Reload.
GATED Mode
0 = Timer counts when the Timer Input signal is High (1) and interrupts are
1 = Timer counts when the Timer Input signal is Low (0) and interrupts are
CAPTURE/COMPARE Mode
0 = Counting is started on the first rising edge of the Timer Input signal. The
1 = Counting is started on the first falling edge of the Timer Input signal. The
PRES—Prescale value
The timer input clock is divided by 2
reset each time the Timer is disabled. This insures proper clock division each time the
Timer is restarted.
000 = Divide by 1
001 = Divide by 2
010 = Divide by 4
011 = Divide by 8
100 = Divide by 16
101 = Divide by 32
110 = Divide by 64
111 = Divide by 128
