2TIMER_START

Writing a ‘1’ to this bit will load the timer counter with the RTOS

Timer Preload Register and start counting. If the Preload Register

is 0, counting will not start and this bit will be cleared to ‘0’.

Writing a ‘0’ to this bit will halt the counter and clear its contents to

0. The RTOS timer interrupt will not be generated.

This bit is automatically cleared if the AUTO_RELOAD bit is ‘0’ and

the timer counter transitions from 1 to 0.
