13.1.3 One-shot Timer Mode
In one-shot timer mode, the timer is activated only once by one trigger. When the trigger occurs, the timer
starts up and continues operating for a given period. Table 13.4 lists the One-shot Timer Mode Specifications.
Figure 13.11 shows Registers TA0MR to TA4MR in One-shot Timer Mode.

• Down-count
• When the counter reaches 0000h, it stops counting after reloading a new value
• 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 0000h.
The TAiS bit in the TABSR register = 1 (count starts) and one of the following
triggers occurs.
• External trigger input from the TAiIN pin
• Timer B2 overflow or underflow,
• The TAiOS bit in the ONSF register is set to 1 (timer starts)
• When the counter is reloaded after reaching 0000h
• TAiS bit is set to 0 (count stops)
I/O port or trigger input
I/O port or pulse output
An undefined value is 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)
• Pulse output function
Timer Aj overflow or underflow,
Timer Ak overflow or underflow
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)
The timer outputs a low when not counting and a high when counting.
n : set value of the TAi register
