11.6.4.2
Operation During Dead Time Timer Mode
The dead-time generator inputs real-time output (RT1, RT3, and RT5) or PPG0 timer
pulse output and outputs a non-overlapping signal (reverse signal) to the external pins
(RTO0 to RTO5).
■ Operation During Dead Time Timer Mode
●
This non-overlapping signal is generated via normal-polarity RT1, RT3, and RT5 (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) = 100
When the DTCR0, DTCR1, and DTCR2 register DMOD2 to DMOD0 selects the non-overlapping signal
with a value of 0 (normal 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 rising edge
or falling edge of the RT1, RT3, and RT5 pins. If the RT1, RT3, and RT5 pulse width is less than the
specified non-overlap time, the 16-bit dead timer starts counting down again from the next RT edge
TMRRH0 to TMRRH2, TMRRL0 to TMRRL2 register value.
