RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
(12) Operation When Error Occurs in PWM Mode 1 and Operation is Restarted in Reset-
Synchronized PWM Mode
Figure 23.127 shows a case in which an error occurs in PWM mode 1 and operation is restarted in reset-synchronized
PWM mode after re-setting.
Figure 23.127 Error Occurrence in PWM Mode 1, Recovery in Reset-Synchronized PWM Mode
(1) to (14) are the same as in Figure 23.126.
(15) Select the reset-synchronized PWM mode output level and enable or disable cyclic output with the TOCR register.
(16) Set reset-synchronized PWM mode.
(17) Enable output in MTU3 and MTU4 with the TOER register.
(18) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(19) Restart operation by setting the TSTR register.
