Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in PWM Mode 2: Figure 9.126 shows an explanatory diagram of the case where an error occurs
in normal mode and operation is restarted in PWM mode 2 after re-setting.
MTU2 module output
1 to 10 are the same as in figure 9.124.
11. Set PWM mode 2.
12. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized. If
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
Note: PWM mode 2 can only be set for channels 0 to 2, and therefore TOER setting is not
initialization is required, initialize in normal mode, then switch to PWM mode 2.)
Port output
n = 0 to 15
necessary.
