Restarted in Normal Mode: Figure 12.96 shows an explanatory diagram of the case where an
error occurs in normal mode and operation is restarted in normal mode after re-setting.

Figure 12.96 Error Occurrence in Normal Mode, Recovery in Normal Mode
1.After a reset, MTU output is low and ports are in the high-impedance state.
2.After a reset, the TMDR setting is for normal mode.
3.For channels 3 and 4, enable output with TOER before initializing the pins with TIOR.
4.Initialize the pins with TIOR.
(The example shows initial high output, with low output on
compare-match occurrence.)
5.Set MTU output with the PFC.
6.The count operation is started by TSTR.
7.Output goes low on compare-match occurrence.
8.An error occurs.
9.Set port output with the PFC and output the inverse of the active level.
10. The count operation is stopped by TSTR.
11. Not necessary when restarting in normal mode.
12.Initialize the pins with TIOR.
13.Set MTU output with the PFC.
14.Operation is restarted by TSTR.
