Q.
The value at the fixed vector table is different from the value set in the program I downloaded. Why?
A.
Since the DBC* vector and BRK instruction vector are used by the emulator, the value on these vector addresses should be different
from what you have specified.
In the emulator, the BRK vector is reserved for the emulator BRK instruction interrupt, and the emulator will modify this vector
data. The vector Jump address (default address 2C00h) indicates the WORK AREA RAM that the PD30 uses. The PD30 modifies
the vector value just before executing the user program. Therefore, you can see the downloaded vector as long as you have not
executed the RUN command.
Please note that this is an emulator-related limitation.
