3.3.1 System Reset Switch
The system reset switch has dual functions. Not only does it initialize the target MCU, but it also establishes
maintenance mode to execute the self-check, etc. when pressed within two seconds after power-on.
If you do not press the switch within two seconds after power-on, the emulator PC7501 and the target MCU are
initialized directly, and ready to accept command input for the emulator debugger M3T-PDxxF. Table 3.3 lists the
functions of the system reset switch.
