Section 8 Multifunction Timer Pulse Unit (MTU)
1 to 10 are the same as in figure 8.84.
11. Set PWM mode 2.
12. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized. If
initialization is required, initialize in normal mode, then switch to PWM mode 2.)
13. Set MTU 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
necessary.
(4) Operation when Error Occurs during Normal Mode Operation, and Operation is
Restarted in Phase Counting Mode
Figure 8.87 shows an explanatory diagram of the case where an error occurs in normal mode and
operation is restarted in phase counting mode after re-setting.
