2.4.10 Reset Events
A reset event sets the device and its internal logic in the default configuration. All user-defined settings are
overwritten with the default values. The list of reset events and their effect is summarized in Table 15.
Note:
As already shown in Figure 11 all reset events will result in an operation mode change. The entered
mode will be OPM0.
