Timer X underflow
Timer Z is an 8-bit timer with an 8-bit prescaler. The prescaler and timer each consist of a reload register and
counter. The reload register and counter are allocated at the same address. Refer to the Tables 14.7 to 14.10 for the
Specifications of Each Mode. Timer Z contains timer Z primary and timer Z secondary reload registers.
Figure 14.11 shows a Block Diagram of Timer Z. Figures 14.12 to 14.15 show registers TZMR, PREZ, TZSC,
TZPR, TZOC, PUM, and TCSS.
Timer Z has the following four operating modes:
TZMOD1 to TZMOD0 = 01b, 10b, 11b
TZMOD0 to TZMOD1, TZS: Bits in TZMR register
TZOS, TZOCNT: Bits in TZOC register

The timer counts an internal count source or timer X
underflows.
The timer outputs pulses of a given width successively.
The timer outputs a one-shot pulse.
The timer outputs a delayed one-shot pulse.
