FUJITSU MB90675-Evaluation Board - User Manual3.3.7. PORT [INTERN | EXTERN]Link Monitor I/Os to a RS232 portSelects the internal UART (UART 0 of the microcontroller) or external UART (on-board chipdevice) for monitor communication. All monitor I/Os are done via this port. After changing theconnector must be plugged in the appropriate interface. Without parameter the current modecan be displayed.Power On default is EXTERN.>port intern↵... Sets the internal UART as monitor port.NOTE: This setting is maintained also after Monitor Reset. However, Power On reset sets thedefault value.3.3.8. UPORT [INTERN | EXTERN]Link BIOS-I/Os to a RS232 portSelects the internal (UART0 of the microcontroller) or external (on-board chip device) UARTfor user communication via BIOS calls. All BIOS I/Os are done via this port. Withoutparameter the current mode can be displayed.Power On default is INTERN.>uport extern↵... Links the BIOS I/Os to the external UART. This way, only one terminal is needed for both,the monitor and the BIOS I/Os.NOTE: This setting is maintained also after Monitor Reset. However, Power On Reset setsthe default value.3.3.9. UBREAK [ON | OFF]Enable User Break functionUser program execution can be stopped by pressing any key of the external port terminal, ifJP37 is enabled. Without parameter the current mode can be displayed.Following controller resources are used: The vector in the user interrupt vector table, theinterrupt control register ICR01, the external interrupt port, the trigger level register, theinterrupt level register and the interrupt enable flag are set. Before every user execution step,interrupt signalling for external interrupt #3 is cleared.NOTE: The CPU interrupt level register and the interrupt enable flag within the processorstate should not be changed. In case the Monitor wants to continue the User program(Trace, Go, Exit or Step) and the processor state is not properly set, the User iswarned and the processor state reset.Do not use this function, if the external interrupt #3 is already used.The User Break interrupt level is "1". FUJITSU Mikroelektronik GmbH 1996 - 21 -
