Timer Counter Bits — The 16-bit main timer is an up counter. A read to this register will return the current value
of the counter.

Timer Enable
0 Disables the main timer, including the counter. Can be used for reducing power consumption.
1 Allows the timer to function normally.
Note: If for any reason the timer is not active, there is no ÷64 clock for the pulse accumulator since the ÷64 is
Timer Module Stops While in Wait
0 Allows the timer module to continue running during wait.
1 Disables the timer counter, pulse accumulators and modulus down counter when the MCU is in wait mode.
