Instructions
For ISP programming, see the P3J pinout in the documentation section.
For DFU USB bootloader mode, just hold the user button as you insert the P3J into the PC USB port. The bootloader is started, and you can load the AT90USB162 DFU drivers from the FLIP installation directory and use FLIP as your programming software.

To compile your own P3J compatible DFU bootloader:

1. Download the latest LUFAlib!

2. Edit the following lines in the makefile:
MCU = at90usb162
BOARD = TEENSY
F_CPU = 16000000
BOOT_START = 0x3000

3. Add the following lines in BootloaderDFU.c right after "int main(void){":
void (*reset)(void)=0;
PORTD=0xFF;
DDRD=1<<6;
if (PIND&(1<<7)) reset();

4. Program over ISP and set the BOOTRST fuse!
