Timer Z is an 8-bit timer with an 8-bit prescaler. The prescaler and timer consist of the reload register and
counter. The reload register and counter are allocated at the same address. Refer to the Tables 13.7 to
13.12 for the Specification of Each Mode. Timer Z contains the timer Z primary and timer Z secondary
as the reload register.
Figure 13.11 shows the Block Diagram of Timer Z. Figures 13.12 to 13.15 show the TZMR, PREZ,
TZSC, TZPR, TZOC, PUM, and TCSS registers.
Timer Z contains 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
