CHAPTER 11 MULTIFUNCTIONAL TIMER
●
This non-overlapping signal is generated via reverse-polarity PPG (16-bit dead timer control register
(DTCR0, DTCR1, and DTCR2) TMD8 to TMD0 (higher-order bits are 10 to 8; lower-order bits are 2 to
0) = 111 ).
B
When the DTCR0, DTCR1, and DTCR2 register's DMOD2 to DMOD0 (higher-order bit is 15; lower-order
bit is 7) selects the non-overlapping signal with a value of 1 (reverse polarity), a delay equivalent to the
non-overlap time set in the 16-bit dead timer register (TMRRH0 to TMRRH2, TMRRL0 to TMRRL2) is
applied. This delay is applied to the PPG0 timer pulse signal or reverse signal's rising edge. If the PPG0
timer pulse width is less than the specified non-overlap time, the 16-bit dead timer starts counting down
again from the TMRRH0 to TMRRH2 and TMRRL0 to TMRRL2 value of the edge following that PPG0
pulse.
