Selectable function
1. Bits CNT3 to CNT0 in the TCSPR register select no division (n = 0) or divide-by-2n (n = 1 to 15).
2. Wait for one or more count source cycles to write after the count starts.
When a trigger occurs, the counter decrements until underflows. Then, the counter is reloaded and stops until
the next trigger occurs.
Table 15.6 lists specifications of one-shot timer mode. Figure 15.18 shows a one-shot timer mode operation.

Specifications of One-Shot Timer Mode
f1, f8, f2n
• Counter decrements
n times
A trigger, selectable from the following, occurs while the TAiS bit in the TABSR
register is set to 1 (count starts):
• the TAiOS bit in the ONSF register is set to 1 (timer starts)
• an external trigger is applied to TAiIN pin
• timer B2 overflows or underflows,
• timer Aj overflows or underflows (j = i - 1, except j = 4 if i = 0),
• timer Ak overflows or underflows (k = i + 1, except k = 0 if i = 4)
• After the counter reaches 0000h and the counter value is reloaded
• When the TAiS bit is set to 0 (count stops)
Trigger input
Pulse output
A read from the TAi register returns undefined value
• A write to the TAi register while the count is stopped:
• A write to the TAi register while counting:
Pulse output function
“L” is output while the count stops. “H” is output while counting.
The value is written to both the reload register and the counter.
The value is written to the reload register (It is transferred to the counter at the
next reload timing).
When the counter reaches 0000h, the counter is reloaded and stops until the
next trigger occurs.
If a trigger occurs while counting, the contents of the reload register are
reloaded into the counter and the count continues.
