• Decrement
• When the timer underflows, it reloads the reload register contents and continues counting
1/(n+1)
Set TAiS bit in the TABSR register to “1” (start counting)
Set TAiS bit to “0” (stop counting)

I/O port or pulse output
Count value can be read by reading TAi register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)

Value written to TAi register is written to both reload register and counter
Value written to TAi register is written to only reload register
Counting can be started and stopped by an input signal to TAi
Whenever the timer underflows, the output polarity of TAi
When not counting, the pin outputs a low.
