Note:
MISO, MOSI & SCK lines can be disconnected when the product is in debugging mode. These
can be used then for application purpose.

Description
Useful to measure the VCC and AVCC current
Connect STK500 REF circuit to AVR AREF
Closed to have a 1K resistor on ISRC pin (1)
Always closed, enable to supply potentiometer
JP5.2 is output of potentiometer to connect either on signal
port on STK500 or ADC input.
UART lines to connect to TxD & RxD line on STK500, see
