Note 1: The waveform output of one-shot pulse is completed after 0.5 clock (1 clock when

primary waveform extended) of fPZ from occurrence of Timer Z interrupt request.

Conditions: Timer Z primary=0316, Timer Z primary waveform not extended,

Timer Z primary=0416, Timer Z secondary waveform not extended,

Timer Z output level latch [TZOPL]=0,

INT0 one-shot trigger is valid at rising edge
