FUJITSU MB90675-Evaluation Board - User Manual

NOTE: On power-on reset the monitor writes a default vector table into the user interrupt

vector area (1 KB from FFC000..FFFFFF ⇔ shadow RAM FBC000..FBFFFF).

The Forced Monitor Reset is intended for the case that the Monitor Reset button does not start

the monitor. Depending on user program and what its initialisation routine sets the control

signals for external bus, P37 can be used as I/O port instead as CLK . In order to trigger

monitor mapping push the Monitor Reset button first, keep it pushed then press User Reset.

Release User Reset first then Monitor Reset.

Finally, the RS232 connectors should be mentioned. The external port is intended for monitor

communication. It is the default port of the monitor shell and uses an external (no controller

resource) UART device. The internal port is the default user program port. So the user

program can benefit from the microcontroller resources. It is possible to exchange the

functionality of the ports or to set both functions the same port (e.g. there is only one terminal

available). However, recommended configuration is a terminal on external UART for monitor

control and a second terminal for user program I/O-operation on internal UART0.
