1. Even when counting the secondary period, read out the TZPR register.
2. The setting value in the TZPR register and TZSC register are made effective by writing a value to
3. The TZOCNT bit is enabled by the followings.
Programmable waveform generation mode is mode to invert the signal output from the TZOUT pin
each time the counter underflows, while the values in the TZPR and TZSC registers are counted
alternately (see Table 13.8 Specification of Programmable Waveform Generation Mode). A
counting starts by counting the value set in the TZPR register. Figure 13.17 shows TZMR and PUM
Registers in Programmable Waveform Generation Mode. Figure 13.18 shows Operating Example of

When the TZOCNT bit in the TZOC register is set to “0”, the output from TZOUT
is inverted synchronously when Timer Z underflows. And when setting to “1”,
