5 Run_ Wait A high indicates the Timer should run continuously while enabled. When the Timer counter
reaches terminal count it immediately resets to 0 and resumes counting. If the Run/Wait bit is
set low, the Timer Counter expires, but then waits until the Timer is cleared (either by writing 1
to the status bit or by disabling and re-enabling the Timer), before resuming operation.
6 Interrupt
Enable
CPU Interrupt is generated only if this bit is high. This bit does not affect operation of the Timer
Counter or Status Bit registers.
7Timer
Enable
While this bit is high the Timer operates normally, while low the Timer is reset and remains idle.
