In programmable one-shot generation mode and programmable wait one-shot generation mode, operation starts
when a one-shot trigger is generated while the TCSTF bit in the TRBCR register is set to 1 (count starts).
A one-shot trigger can be generated by either of the following causes:
• 1 is written to the TOSST bit in the TRBOCR register by a program.
• Trigger input from the INT0 pin.
When a one-shot trigger occurs, the TOSSTF bit in the TRBOCR register is set to 1 (one-shot operation in
progress) after one or two cycles of the count source have elapsed. Then, in programmable one-shot generation
mode, count operation begins and one-shot waveform output starts. (In programmable wait one-shot generation
mode, count operation starts for the wait period.) If a one-shot trigger occurs while the TOSSTF bit is set to 1,
no retriggering occurs.
To use trigger input from the INT0 pin, input the trigger after making the following settings:
• Set the PD4_5 bit in the PD4 register to 0 (input port).
• Select the INT0 digital filter with bits INT0F1 and INT0F0 in the INTF register.
• Select both edges or one edge with the INT0PL bit in INTEN register. If one edge is selected, further select
• Set the INT0EN bit in the INTEN register to 0 (enabled).
• After completing the above, set the INOSTG bit in the TRBIOC register to 1 (INT pin one-shot trigger
Note the following points with regard to generating interrupt requests by trigger input from the INT0 pin.
• Processing to handle the interrupts is required. Refer to 11. Interrupts, for details.
• If one edge is selected, use the POL bit in the INT0IC register to select falling or rising edge. (The INOSEG
