(11) Operation When Error Occurs in PWM Mode 1 and Operation is Restarted in Complementary
PWM Mode
Figure 19.153 shows a case in which an error occurs in PWM mode 1 and operation is restarted in complementary
PWM mode after re-setting.

(1) to (10) are the same as in Figure 19.149 .
(11) Set normal mode to initialize the normal mode waveform generation block.
(12) Initialize the PWM mode 1 waveform generation block with the TIOR register.
(13) Disable operation of the PWM mode 1 waveform generation block with the TIOR register.
(14) Disable output in MTU3 and MTU4 with the TOERA register.
(15) Select the complementary PWM output level and enable or disable cyclic output with registers TOCR1A and
TOCR2A.
(16) Set complementary PWM mode.
(17) Enable output in MTU3 and MTU4 with the TOERA register.
(18) Set MTU output using the MPC and port mode registers (PMR) corresponding to the I/O ports.
(19) Restart operation by setting the TSTRA register.
