The DIO pin names are specified as PnXb, where
n : means the connector reference number n=1-2
X : means the port name, X= A, B or C
b : means the bit number of a port, b=0-7
For example, P1C4 means bit 4 of port C on connector CN1
EXTCLK: External edge trigger signal for latch digital input
data
EVENT : External clock source for counter 0
V5V : Onboard un-regulated 5V power supply output
+12V : Onboard un-regulated +12V power supply output
