I program it in ATXMEGA64A3U.
I made LED brinking program PBPORT0 - 7 turned onoff.
The LED which I connected to PBPORT0 - 3 turned on.
but,PBPORT4 - 7 LED I can't blinking.
According to the data sheet, PBPORT4~7 was written as JTAG pin.
I found MCU Control register's JTAGD bit.
When I tried to set JTAGD bit in JTAGICE3 debugging mode , but I can't.
JTAG function seems to become invalid if I set JTAGD bit, would you tell me how to change this bit?
