Disable JTAG in WinAVR

Disable JTAG in WinAVR

do it very simple:

#define JTAG_Set(x) \
{ \
        __asm__ __volatile__ ( \
                "in __tmp_reg__,__SREG__" "\n\t" \
                "cli" "\n\t" \
                "out %1, %0" "\n\t" \
                "out __SREG__, __tmp_reg__" "\n\t"\
                "out %1, %0" "\n\t" \
                : /* no outputs */ \
                : "r" ((uint8_t)(x ? (1<                  "M" (_SFR_IO_ADDR(MCUCSR)) \
                : "r0"); \
}

use it just like this:

JTAG_Set(1); // disable JTAG port
