(89h) : Timer/Counter 0 Mode Control Register
C/T
: Counter or Timer Selector. Cleared for Timer operation
while INTx pin is high (hardware control). When GATE=0,
Timer x will run only while TRx=1 (software control).
(input from internal system clock). Set for Counter operation
(input from Tx input pin).
(Timer 1) stopped, (Timer 0)
