Dear Marshall,

Is there any way that I can change the location of the pointer to use XDATA space. I am using SILABS C8051F047 and Raisonance C Compiler. Thanks and Regards Marshall Brown Have you read datasheets of your MCU & compiler? Does your part has onchip xram? (If not you can add external if device has address+data bus & read/write signals) As how to use xdata space; the datasheet for compiler can be useful(normally you can instruct compiler while declaring the variable, at least it works with Keil as well as SDCC.) Welll I am not familiar to Raisonance compiler or even your part of MCU. But this is normal practise to refer datasheet. Regards, Mahesh |
