RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
(5) Operation When Error Occurs in Normal Mode and Operation is Restarted in Complementary
PWM Mode
Figure 23.120 shows a case in which an error occurs in normal mode and operation is restarted in complementary PWM
mode after re-setting.

(1) to (10) are the same as in Figure 23.116.
(11) Initialize the normal mode waveform generation block with the TIOR register.
(12) Disable operation of the normal mode waveform generation block with the TIOR register.
(13) Disable output in MTU3 and MTU4 with the TOER register.
(14) Select the complementary PWM mode output level and enable or disable cyclic output with the TOCR register.
(15) Set complementary PWM mode.
(16) Enable output in MTU3 and MTU4 with the TOER register.
(17) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(18) Restart operation by setting the TSTR register.
