written values are reflected to the waveform output from the next primary period after writing to the TYPR register.
Therefore, pulse is output from the next primary period depending on the setting value of the TYOCNT bit.
12.2.2 Programmable Waveform Generation Mode
In this mode, an signal output from the TY
the values in the TYPR register and TYSC register are counted alternately (see “Table 12.8 Program-
mable Waveform Generation Mode Specifications”). A counting starts by counting the set value in the
TYPR register. Figure 12.16 shows the TYZMR register in programmable waveform generation mode.
Figure 12.17 shows the operation example.

The output level during primary and secondary periods is selected by the TYOPL bit.
When the TYOCNT bit in the TYZOC register is set to “0”, the output from TY
inverted synchronously when Timer Y underflows during the secondary period. And
when set to “1”, a value in the P3_2 bit is output from TY
Y underflows during the secondary period
