Hi,
Thanks!
the sample code is :
/*******************************************************************************/
/* cmd line:sdcc -mpic14 -p16f84 test.c */
#define MREAD_BYTE(addr) *((unsigned char *)(addr))
void func2 (int,int);
void test_func1 (int var1)
{
unsigned char byCSR0;
byCSR0 = MREAD_BYTE(1);
/* if cut sub 3 line, the error is lost
*/
if (byCSR0 ) {
func2 (1, 1);
}
return;
}
void func2 (int var1,int var2)
{
var1 = var2;
var2 = var1;
}
