Note on MMT Dead Time: The dead time (non-overlap time) may be shorter than the value set in
the time dead time register (MMT_TDDR), or a silent (consisting of 0s) PWM waveform may be

To prevent the problem from occurring, implement either A or B below.
1. Set the CST bit to 1 and do not clear it after MMT counting begins. If there is a need to clear
2. In order to set, clear, and then reset the CST bit, use the following procedure for clearing and

resetting.
(1) Set the PWM output pin as a general input port in the MMT pin control register.
(2) Set a value of H'0000 in the free operation addresses of all the buffer registers (TBRU,
(3) After the set dead time interval has elapsed set TCNR to H'00 and clear the CST bit to 0.
(4) Reset the CST bit to 1.
