Table 12.12 Programmable Wait One-shot Generation Mode Specifications
NOTES:
1. The TZS bit in the TYZMR register must be set to "1" (start counting).
2. The TZS bit must be set to "1" (start counting), the INT0EN bit in the INTEN register to "1" (enabling INT0 input), and
3. The set values are reflected beginning with the next one-shot pulse after writing to the TZPR register.

12.3.4 Programmable Wait One-shot Generation Mode
In this mode, upon program or external trigger input (input to the INT0 pin), the microcomputer outputs
the one-shot pulse from the TZ
Programmable Wait One-shot Generation Mode Specifications”). When a trigger occurs, from this
point, the timer starts outputting pulses only once for a given length of time equal to the set value in the
TZSC register after waiting for a given length of time equal to the set value in the TZPR register.
Figure 12.26 shows the TYZMR and PUM registers in this mode. Figure 12.27 shows an operation
example in this mode.
