Timer Y underflow
Timer Z is an 8-bit timer with an 8-bit prescaler and has two reload registers-Timer Z Primary and Timer
Z Secondary. Figure 12.18 shows a block diagram of Timer Z. Figures 12.19 to 12.21 show the TYZMR,
PREZ, TZSC, TZPR, TYZOC, PUM, and TCSS registers.
Timer Z has the following four operation modes.

• Timer mode: The timer counts an internal count source or Timer Y underflow.
• Programmable waveform generation mode: The timer outputs pulses of a given width successively.
• Programmable one-shot generation mode: The timer outputs one-shot pulse.
• Programmable wait one-shot generation mode: The timer outputs delayed one-shot pulse.
