Notes Concerning Dead Time Control in HT-PWM Mode
(a)
TSnDTC0 and TSnDTC1 Rewriting
It is possible to rewrite the dead time setting in TSnDTC0 and TSnDTC1
registers during timer operation.
Caution 1.
Rewrite TSnDTC0 and TSnDTC1 when the reload function is used (TSnRMC
= 0).
Caution 2. The write protection code check function is applied when TSnDTC0 and
TSnDTC1 are rewritten. Refer to the pertinent register description for details.
Caution 3. When the TSnCMP0 and TSnDTC1 are updated at the peak of the 16-bit
counter:
When a match occurs between the TSnCMPm set value and the updated
TSnCMP0-TSnDTC1 (new maximum value with the main counter), the match
interrupt (INTTSG2nIm) will not be generated immediately after reload (m = 02,
06, 10).
Caution 4. When the TSnDTC0 is updated at the valley of the 16-bit counter:
When a match occurs between the TSnCMPm set value and the updated
TSnDTC0 (new minimum value with the main counter), the match interrupt
(INTTSG2nIm) is not generated immediately after reload (m = 01, 05, 09).
