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.
