Remarks 1. If transfer (match between the value of the 16-bit counter and the value of the CCR0 buffer
The transfer timing in Figure 11-28 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).

register) occurs in the 6-phase PWM output mode, the value of the TAB1CCR0 register plus 1 is
loaded to the 16-bit counter. In this way, the expected wave can be output even if the cycle value
is changed at the transfer timing of the crest (match between the 16-bit counter value and the
TAB1CCR0 register value) timing.
