GATE
Gating control when set. Timer/Counter ‘x’ is enabled only while
‘INTx’ pin is HIGH and ‘TRx’ control pin is set. When cleared,
Timer ‘x’ is enabled whenever ‘TRx’ control bit is set.
C/T
Gating Timer or Counter Selector cleared for Timer operation
(input from internal system clock.) Set for Counter operation (input
from ‘Tx’ input pin).
