APPLICATION

2.5 Timer Y and timer Z

(3) Application example of programmable wait one-shot generation mode

Outline: The wait one-shot pulse synchronized with the PWM waveform output from the P01/TYOUT

pin is generated from Timer Z by using the programmable waveform generation mode of

Timer Y.

Specifications:TYOUT pin is connected to the P37/INT0 pin. The wait one-shot pulse is output by the

INT0 pin input as trigger.

Operation clock: f(XIN) = 8 MHz, high-speed mode

As for the usage of Timer Y, refer to the above mentioned programmable waveform generation mode.

Figure 2.5.39 shows an example of waveform generation and peripheral circuit. Figure 2.5.40 shows

an example of control procedure.
