ATtiny 2313V JTAG connection
The ATtiny2313, ATtiny2313V, and ATtiny2313A all use the exact same signature ID bytes for ISP purposes. If you're using the JTAGICE mkII in ISP mode, then an ATtiny2313V should...

JTAG connection pin numbers
ATmega328 doesn't support JTAG debugging. Instead, it uses debugWire for in-circuit debugging. In general, if your board includes Atmel's 6-wire ISP connector, then it's probably...
