Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in Normal Mode: Figure 11.97 shows an explanatory diagram of the case where an error occurs
in PWM mode 2 and operation is restarted in normal mode after re-setting.
1. After a reset, MTU output is low and ports are in the high-impedance state.
2. Set PWM mode 2.
3.
4. Set MTU output with the PFC.
5. The count operation is started by TSTR.
6. Output goes low on compare-match occurrence.
7. An error occurs.
8. Set port output with the PFC and output the inverse of the active level.
9. The count operation is stopped by TSTR.
10. Set normal mode.
11. Initialize the pins with TIOR.
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.

compare-match occurrence. In PWM mode 2, the cycle register pins are not initialized. In the
example, TIOC *A is the cycle register.)
Initialize the pins with TIOR. (The example shows initial high output, with low output on
