11.8.3
If an error occurs during MTU operation, MTU output should be cut by the system. Cutoff is
performed by switching the pin output to port output with the PFC and outputting the inverse of
the active level. For large-current pins, output can also be cut by hardware, using port output
enable (POE). The pin initialization procedures for re-setting due to an error during operation, etc.,
and the procedures for restarting in a different mode after re-setting, are shown below.
The MTU has six operating modes, as stated above. There are thus 36 mode transition
combinations, but some transitions are not available with certain channel and mode combinations.
Possible mode transition combinations are shown in table 11.43.
