ایراد از ماکرو های برنامه!

[omid_phoenix]

سلام
تو برنامه ای که گذاشتم از این چندتا ماکرو، warning میگیره

کد:

#define RXB8 1
#define TXB8 0
#define UPE 2
#define OVR 3
#define FE 4
#define UDRE 5
#define RXC 7

البته برنامه کامپایل میشه ولی میخوام علت warning ها رو بدونم

کد:

#include <mega32.h>

#asm
   .equ __lcd_port=0x15 ;PORTC
