13.1.1 Timer Mode
In timer mode, the timer counts a count source generated internally.
Table 13.1 lists the Timer Mode Specifications. Figure 13.7 shows Registers TA0MR to TA4MR in Timer Mode.

• Down-count
• When the timer underflows, it reloads the reload register contents and continues counting
1/(n+1)
Set the TAiS bit in the TABSR register to 1 (count starts)
Set the TAiS bit to 0 (count stops)
I/O port or gate input
I/O port or pulse output
Count value can be read by reading the TAi register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
• Gate function
• Pulse output function
b0
Value written to the TAi register is written to both reload register and counter
Value written to the TAi register is written to only reload register
(Transferred to counter when reloaded next)
Counting can be started and stopped by an input signal to TAiIN pin
Whenever the timer underflows, the output polarity of TAiOUT pin is inverted.
When TAiS bit is set to 0 (count stops), the pin outputs a low.
