Bit No.	7	6		5	4	3	2	1	0

Name					POL	ADCH3	ADCH2	ADCH1	ADCH0

POL	Optocoupler polarity jumper setting; the value indicates the value of an open
	circuit:

1Open circuit reads as 1, “high” input reads as 0

0Open circuit reads as 0, “high” input reads as 1

ADCH3 - 0 Current A/D channel; this is the channel currently selected on board and is the channel that will be used for the next A/D conversion (unless a new value is written to the channel register before then).
