Operation when Error Occurs during Phase Counting Mode Operation, and Operation is
Restarted in Normal Mode: Figure 11.101 shows an explanatory diagram of the case where an
error occurs in phase counting mode 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 phase counting mode.
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 in normal mode.
11. Initialize the pins with TIOR.
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.
