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

12.3.3 Programmable One-shot Generation Mode
In this mode, upon program command or external trigger input (input to the INT0 pin), the microcom-
puter outputs the one-shot pulse from the TZ
Generation Mode Specifications”). When a trigger occurs, the timer starts operating from the point
only once for a given period equal to the set value in the TZPR register. The TZSC is unused in this
mode. Figure 12.24 shows the TYZMR register and PUM register in this mode. Figure 12.25 shows
an operation example in this mode.
