He has info on this at Embedded.com. Essential reading!
You should also include volatile in case the address refers to a register that has inputs (can change value at times other than just when the CPU is writing to it): #define AnSL811reg *((volatile char far *)0x07F7FF) Here is one I used: #define FPGABASEADDR 0x8000 #define FANREG1 *(volatile U8 xdata * const)(FPGABASEADDR+0x4B) #define FANREG2 *(volatile U8 xdata * const)(FPGABASEADDR+0x4C) : etc |
