• This bit activates or stops the counter.
• Setting this bit to "1" from "0" clears the counter. If the timer is
operating continuously (T1STP = "0") at this time, the counter starts
operation to increment the count in synchronization with the selected
count clock. Writing "0" to this bit stops counter operation.
• When the timer is activated (T1STP ="0" --> "1") in 16-bit mode, the
timer 1 and timer 2 counters are both cleared.
