AND R0,R0,#0XFFFFFF7F

I have tried with __ASM attribute but it gives error

if you want to do inline programing like c with asm the use # pragma Asm and end pragma commamds.
you can also write your asm code in seperate file in a subroutine.
you will have to define and declear the asm function.
also use compile through .src in the compiler control menu.

Can you give me exact code for above three lines in inline assebly
It is necessery to me as I have to insert assembly statements several times.
Actually it is irritating to make assebly function every time

Thanks and regards

Hi girish_wabale,

I do not know keil, but you can try following code.

#asm

MRS R0 ,CPSR

AND R0,R0,#0XFFFFFF7F

MSR CPSR,R0

#endasm

best luck,
