Description	The IBANKING directive specifies that the linker use the on-chip code banking hardware of the Mentor M8051EW core, the Infineon SDA30C16x/26x, and the Micronas SDA555x devices. When this directive is specified, the linker places all code segments without a ?CO prefix or suffix into the bank area. Segments with a ?CO prefix or suffix are placed in the common area. The L51_BANK.A51 code banking configuration file is not used. The linker generates a jump table with the following format: MOV bank_sfr, #BANK_NUMBER LJMP target Note Using code banking with the IBANKING directive requires special run-time libraries (named *C51M.LIB) that are automatically selected when you specify the IBANKING** directive.
