MODIFYING THE DEFAULT BANK-SWITCHING ROUTINE
The default bank-switching code is available in the supplied assembler language source
file iar_banked_code_support.s51, which you can find in the directory
8051\src\lib.
The bank-switching routine is based on an SFR port being used for the bank switching.
By default P1is used. The SFR port is defined inthe linker command file by the line:
-D?CBANK=PORTADDRESS
As long as you use this solution, the only thing you must do is to define the appropriate
SFR port address.
After you have modified the file, reassemble it and replace the object module in the
runtime library you are using. Simply include it in your application project and it will
be used instead of the standard module in the library.
