23. Multi-Function Timer Pulse Unit 2 (MTU2a)
(25) Operation When Error Occurs in Complementary PWM Mode and Operation is Restarted in
Reset-Synchronized PWM Mode
shows a case in which an error occurs in complementary PWM mode and operation is restarted in reset-
synchronized PWM mode after re-setting.

Error Occurrence in Complementary PWM Mode, Recovery in Reset-Synchronized PWM Mode
(1) to (10) are the same as in
(11) Set normal mode (MTU output goes low).
(12) Disable output in MTU3 and MTU4 with the TOER register.
(13) Select the reset-synchronized PWM mode output level and enable or disable cyclic output with the TOCR register.
(14) Set reset-synchronized PWM mode.
(15) Enable output in MTU3 and MTU4 with the TOER register.
(16) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(17) Restart operation by setting the TSTR register.
