FUJITSU MB90675-Evaluation Board - User Manual
Note also, that switching the microcontroller into the STOP, SLEEP or WATCH modes will
disable monitor control via the terminal. After reset the user break function is always disabled.
When the monitor is active, it always configures the clock control for max. speed. The user
program speed is saved and restored when control is given to the user program.
The speed is pre-defined to 16 MHz machine clock (4 MHz main clock).
Recommendations:
1.) Hex download
Depending on the version of "LMC907A.EXE" (the tool to generate a HEX-file from an ABS-
file) a start vector which points to program entry point is appended. However, the bank of this
vector is always 0Fh, even if the "_start" function has been linked to another bank.
The download procedure of the monitor uses this vector (if appended) to set it as PCB and PC
register. In order to start a program include the __set_vector() function and use the User Reset
instead of typing "GOTO" without parameters.
