(b) Rewriting TQ1CCR0 register
The transfer timing in Figure 9-28 is at the point where the crest timing occurs. While the 16-bit counter is
counting down, the cycle changes and an asymmetrical triangular wave is output. Because the cycle
changes, rewrite the duty factor (voltage data value).
When rewriting the TQ1CCR0 register in the batch rewrite mode, the output waveform differs depending
on whether transfer occurs at the crest (match between the 16-bit counter value and TQ1CCR0 register
value) or at the valley (match between the 16-bit counter value and 0001H). Usually, it is recommended to
rewrite the TQ1CCR0 register while the 16-bit counter is counting down, and transfer the register value at
the transfer timing of the valley timing.
Figure 9-28 shows an example of rewriting the TQ1CCR0 register while the 16-bit counter is counting up
(during period <1> in Figure 9-27). Figure 9-29 shows an example of rewriting the TQ1CCR0 register
while the counter is counting down (during period <2> in Figure 9-27).
