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
