CHAPTER 11 MOTOR CONTROL FUNCTION
(b) Rewriting TAB1CCR0 register
When rewriting the TAB1CCR0 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 TAB1CCR0 register
value) or at the valley (match between the 16-bit counter value and 0001H). Usually, it is recommended to
rewrite the TAB1CCR0 register while the 16-bit counter is counting down, and transfer the register value at
the transfer timing of the crest timing.
Figure 11-28 shows an example of rewriting the TAB1CCR0 register while the 16-bit counter is counting up
(during period <1> in Figure 11-27). Figure 11-29 shows an example of rewriting the TAB1CCR0 register
while the counter is counting down (during period <2> in Figure 11-27).
