Default Settings

Assuming CBIT 1 is connected to H1-P3 and CBIT 2 is connected to H1-P6 the following is true.

Switch control string for SW1: NO = XXXXXXX0 or C10, NC = XXXXXXX1 or C11
Switch control string for SW2: NO = XXXXXX0X or C20, NC = XXXXXX1X or C21

X = don't care
1 = CBIT pulled high
0 = CBIT pulled low

NO = normally open
NC = normally closed
