I suppose your code should be like the followings instead of yours

#define T1STAT_CH4IF 0x10

if (T1STAT && T1STAT_CH4IF )) {
T1STAT = ~T1STAT_CH4IF;
}

Hlw Sir,

Here is the code for remote.c

#include "hal_mcu.h"
#include "remote.h"
#define T1STAT_CH4IF 0x10

void Remoteinit(void)
{

PERCFG &= (~(0x40));
// P2DIR |= 0x0;

//T1STAT |= 0x10;

T1CTL |= 0x08; //3
T1CCTL4 |= 0x40;

T1CCTL4 |= 0x80;
T1CCTL4 |= (~(0x04));
T1CCTL4 |= 0x02;

// T1CTL |= 0x08;

}

if (T1STAT && T1STAT_CH4IF )
{

T1STAT = ~T1STAT_CH4IF;

void Remoteinit(void);

}

Here is code for remote.h

#ifndef REMOTE_H
#define REMOTE_H

#include "hal_types.h"

// Function prototypes
extern void Remoteinit(void);

#endif

Do you add "#define T1STAT_CH4IF 0x10" in your C file?

You should use "#include “ioCC2541.h”" instead of "#include ioCC2541.h"

Why do you put if statement outside a function? I suggest you to study C Programming skill first.
