11.8.3 Operation in Case of Re-Setting Due to Error during Operation, etc.
If an error occurs during operation of this module, the module output should be cut by the system.
Cutoff is performed by switching the pin output to port output with the general I/O port and
outputting the inverse of the active level. 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.
This module 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 11.57.
