Q.
I am using the M38199MF MCU. This MCU has 2K bytes of on-chip SRAM (40h - 83Fh). But I can not change the contents of the
SRAM located at address 440H or later on my debugger. How I can reconfigure my debugger for this MCU?
A.
To use M38199MF with your debugger, the emulator MCU must be M38197RFS. However, this emulator MCU has just 1K byte of
on-chip SRAM (40h - 43Fh). This is causing your problem. To enable data access for 440h or later RAM address spaces, please
configure addresses 440h - 83Fh as internal RAM using the MAP command. By setting the MAP command to Internal, the on-board
memory becomes accessible. This MAP command configures the on-board SRAM of the emulation pod to perform as the MCU
on-chip RAM, allowing the user to access RAM space 440h - 83Fh.
