RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
(22) Operation When Error Occurs in Complementary PWM Mode and Operation is Restarted in
PWM Mode 1
Figure 23.137 shows a case in which an error occurs in complementary PWM mode and operation is restarted in PWM
mode 1 after re-setting.
Figure 23.137 Error Occurrence in Complementary PWM Mode, Recovery in PWM Mode 1
(1) to (10) are the same as in Figure 23.136.
(11) Set PWM mode 1 (MTU output goes low).
(12) Initialize the pins with the TIOR register. (In PWM mode 1, a waveform is not output on the MTIOCnB
(MTIOCnD) pins. If a level is to be output, make the required general output port settings in the I/O port’s port
direction register (PDR) and port output data register (PODR).)
(13) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(14) Restart operation by setting the TSTR register.
