Resistor reference analog I/O pin. A resistor, R
and GND, as shown in
biases internal analog circuitry. Less accurate resistors cannot be used and will render the
ISP1505 unusable.
The DP (data plus) and DM (data minus) are USB differential data pins. These must be
connected to the D+ and D pins of the USB receptacle.
