RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
(19) Operation When Error Occurs in Phase Counting Mode and Operation is Restarted in PWM
Mode 2
Figure 23.134 shows a case in which an error occurs in phase counting mode and operation is restarted in PWM mode 2
after re-setting.
Figure 23.134 Error Occurrence in Phase Counting Mode, Recovery in PWM Mode 2
(1) to (9) are the same as in Figure 23.132.
(10) Set PWM mode 2.
(11) 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).)
(12) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(13) Restart operation by setting the TSTR register.
(20) Operation When Error Occurs in Phase Counting Mode and Operation is Restarted in Phase
Counting Mode
Figure 23.135 shows a case in which an error occurs in phase counting mode and operation is restarted in phase
counting mode after re-setting.

(1) to (9) are the same as in Figure 23.132.
(10) This step is not necessary when restarting in phase counting mode.
(11) Initialize the pins with the TIOR register.
(12) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(13) Restart operation by setting the TSTR register.
