Description
SWPORT2
Software programmable port 2.
If SWPORT2 = 0, then
pin SWPORT2 is inactive (high-impedance). If SWPORT2 = 1, then
pin SWPORT2 is active (pull down to ground).
SWPORT1
Software programmable port 1.
If SWPORT1 = 0, then
pin SWPORT1 is inactive (high-impedance). If SWPORT1 = 1, then
pin SWPORT1 is active (pull down to ground).
AMNB
AM noise blanker.
If AMNB = 0, then the AM noise blanker is off. If
AMNB = 1, then the AM noise blanker is on.
