Caution on timer output in high-accuracy T-PWM mode
There are cautions for TRnCCR1 to TRnCCR3 as follows when varying 6-phase PWM duty by
using reload (batch rewrite).
(a) In case of T 2
≤
TRnCCRm (Setting prohibited)
Figure 10-63a shows the case when the value of “T 2 or more” is set to the TRnCCR1
register. When the TRnCCR1 register setting is changed like this, a match between the 16-bit
counter and TRnCCR1 register does not occur thereafter. Therefore, the TORn1 pin output level is
forcibly changed to inactive level at the following 16-bit sub-counter trough timing. Output will be
switched at 16-bit sub-counter peak/trough timing after that.
