In programmable one-shot generation mode, a one-shot pulse is output from the TRBO pin by a program or an
external trigger input (input to the INT0 pin) (refer to Table 18.4). When a trigger is generated, the timer starts
operating from the point only once for a given period equal to the set value in the TRBPR register. The TRBSC
register is not used in this mode.
Figure 18.4 shows an Operating Example in Programmable One-Shot Generation Mode.

• The setting value of the TRBPR register is decremented.
• When the timer underflows, it reloads the contents of the reload register before
• When the count stops, the timer reloads the content of the reload register before

• 1 (one-shot starts) is written to the TOSST bit in the TRBOCR register.
• Trigger input to the INT0 pin
• 1 (one-shot stops) is written to the TOSSP bit in the TRBOCR register.
• 0 (count stops) is written to the TSTART bit in the TRBCR register.
• 1 (count forcibly stops) is written to the TSTOP bit in the TRBCR register.

• When the INOSTG bit in the TRBIOC register is set to 1 (INT0 one-shot trigger
The count value can be read out by reading registers TRBPR and TRBPRE.
