(10) Cautions on dead time control in high-accuracy T-PWM mode
(a) Rewriting of TRnDTC0 and TRnDTC1 registers
The setting of the dead time in the TRnDTC0, TRnDTC1 registers can be rewritten during opera-
tion. Note the following cautions when rewriting the dead time setting during operation.
Cautions: 1. Rewrite the TRnDTC0 and TRnDTC1 registers when using the reload function
(TRnCMS = 0).
2. When the TRnDTC0 and TRnDTC1 registers are rewritten, carrier-wave cycles will
be changed. In cases where carrier-wave cycles should not be changed, rewrite
the TRnCCR0 register value at the same time as changing the TRnDTC0 and
TRnDTC1 registers.
3. Rewriting is prohibited when TRnCMS = 1.
4. In case of changing TRnCCR0 and TRnCCR1 at a 16-bit counter peak:
Match interrupts (INTTRnCC1 to INTTRnCC5) will not occur immediately after
reload execution if the values set in the TRnCCR1 to TRnCCR5 register matches
with and TRnCCR0
−
TRnDTC1 (the new maximum value of main counter) after
updating.

5. In case of changing TR0DTC0 at a 16-bit counter trough:
Match interrupts (INTTRnCC1 to INTTRnCC5) will not occur immediately after
reload execution if the values set in the TRnCCR1 to TRnCCR5 register match
with TR0DTC0 (the new minimum value of main counter) after updating.
