In one-shot timer mode, the timer is activated only once by one trigger. (See Table 12.4) When the
trigger occurs, the timer starts up and continues operating for a given period. Figure 12.11 shows the
TAiMR register in one-shot timer mode.

• Decrement
• When the counter reaches 0000
• If a trigger occurs when counting, the timer reloads a new count and restarts counting
1/n
However, the counter does not work if the divide-by-n value is set to 0000
• The TAiOS bit in the ONSF register is set to “1” (timer starts)
• When the counter is reloaded after reaching “0000
• TAiS bit is set to “0” (stop counting)

TAiS bit in the TABSR register is set to “1” (start counting) and one of the
following triggers occurs.
• External trigger input from the TAi
• Timer B2 overflow or underflow,
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
• Pulse output function

Value written to TAi register is written to both reload register and counter
Value written to TAi register is written to only reload register
(Transferred to counter when reloaded next)
The timer outputs a low when not counting and a high when counting.
