(2) Operation When Error Occurs in Normal Mode and Operation is Restarted in PWM Mode 1
Figure 19.144 shows a case in which an error occurs in normal mode and operation is restarted in PWM mode 1 after
re-setting.

(1) to (10) are the same as in Figure 19.143 .
(11) Set 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.
(3) Operation When Error Occurs in Normal Mode and Operation is Restarted in PWM mode 2
Figure 19.145 shows a case in which an error occurs in normal mode and operation is restarted in PWM mode 2 after
re-setting.

Figure 19.145 Error Occurrence in Normal Mode, Recovery in PWM Mode 2
(1) to (10) are the same as in Figure 19.143 .
(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.
