5START

This bit triggers the timer counter. The counter will operate until it

hits its terminating condition. This will clear this bit. It should be

noted that when operating in restart mode, there is no terminating

condition for the counter, so this bit will never clear. Clearing this bit

will halt the timer counter.

Setting this bit will:

• Reset the clock divider counter.

• Enable the clock divider counter.

• Start the timer counter.

• Clear all interrupts.

Clearing this bit will:

• Disable the clock divider counter.

• Stop the timer counter.
