19. Multi-Function Timer Pulse Unit 3 (MTU3c)
(8) Operation When Error Occurs in PWM Mode 1 and Operation is Restarted in PWM mode 1
shows a case in which an error occurs in PWM mode 1 and operation is restarted in PWM mode 1 after
re-setting.

Error Occurrence in PWM Mode 1, Recovery in PWM Mode 1
(1) to (10) are the same as in
(11) This step is not necessary when restarting in PWM mode 1.
(12) Initialize the pins with the TIOR register. (In PWM mode 1, waveforms are not output to the MTIOCnB
(MTIOCnD) pins. To output a specified level, make necessary settings for general output ports in the port direction
registers (PDR) and port output data registers (PODR) of the I/O ports.)
(13) Set MTU output using the MPC and port mode registers (PMR) corresponding to the I/O ports.
(14) Restart operation by setting the TSTRA register.
(9) Operation When Error Occurs in PWM Mode 1 and Operation is Restarted in PWM mode 2
shows a case in which an error occurs in PWM mode 1 and operation is restarted in PWM mode 2 after
re-setting.
Figure 19.151
Error Occurrence in PWM Mode 1, Recovery in PWM Mode 2
(1) to (10) are the same as in
(11) Set PWM mode 2.
(12) Initialize the pins with the TIOR register. (In PWM mode 2, a waveform is not output to the pin that corresponds to
the TGR register used as a period register. To output a specified level, make necessary settings for general output
ports in the port direction registers (PDR) and port output data registers (PODR) of the I/O ports.)
(13) Set MTU output using the MPC and port mode registers (PMR) corresponding to the I/O ports.
(14) Restart operation by setting the TSTRA register.
Note:
PWM mode 2 can only be selected for MTU0 to MTU2, and therefore the TOERA register setting is not
necessary.
