(27) Operation When Error Occurs in Reset-Synchronized PWM Mode and Operation is Restarted
in PWM Mode 1
Figure 19.169 shows a case in which an error occurs in reset-synchronized PWM mode and operation is restarted in
PWM mode 1 after re-setting.

(1) to (10) are the same as in Figure 19.168 .
(11) Set PWM mode 1 (positive-phase MTU output goes low, and negative-phase output goes high).
(12) Initialize the pins with the TIOR register. (In PWM mode 1, waveforms are not output to the MTIOCnB
(MTIOCnD) pins. To output a specified level, make necessary settings for general output ports in the port direction
registers (PDR) and port output data registers (PODR) of the I/O ports.)
(13) Set MTU output using the MPC and port mode registers (PMR) corresponding to the I/O ports.
(14) Restart operation by setting the TSTRA register.
