(Q) .set directives - Ki-Young Park - Jan 27 13:31:00 2001

I like to control AIC in EVM5409 from Spectrum Digital (AD50). I found some example code in asm file to do that and now I like to call those functions from 'C' file. In example source code, many initializations are done using .set command at the beginning of code like IMR .set 000h I_SPCR1 . set 00020h p0_serialflag .set 060h I tried substituting those code with STM asm command like 'STM #000h, IMR' but c compiler(CC1.2) don't know some of those registers' name and gives compile time error.(But it produces object file which I can't understand as well) and of course the resulting object code doesn't work correctly. I think those initialization must be done before the use of AIC. welcome any comments and advice. Thank you |

It is setting up the memory locations for those registers. Brian ----------------------------------------------------- Brian C. Lane Programmer www.shinemicro.com RF & Microcontroller Design |
