Address

008516

When reset

FF16

Function

Values that can be set

Timer mode

Internal count source or Timer Y underflow is counted

0016 to FF16

Programmable waveform generation mode

Internal count source or Timer Y underflow is counted

0016 to FF16

Programmable one-shot generation mode

Internal count source or Timer Y underflow is counted

0016 to FF16

Programmable wait one-shot generation mode

Internal count source or Timer Y underflow is counted

0016 to FF16

Note 1: When using the waveform extend function, set the value "0016" for the Prescaler Z.

Timer Z Primary

Symbol

TZPR

Address

008716

When reset

FF16

Function

Values that can be set

0016 to FF16

Note 1: Each value of Timer Z Primary and Timer Z Secondary is reloaded to the Timer Z alternately for counting.

Timer Z Secondary

Symbol

TZSC

Address

008616

When reset

FF16

Function

Values that can be set

Timer mode

Invalid

Programmable waveform generation mode

Underflow of Prescaler Z is counted (Note 1)

0016 to FF16

Programmable one-shot generation mode

Invalid
