MISC CONTROL PORT PINS
PIN NAME
PIN I/O TYPE
DESCRIPTION
ANTSEL
O
The antenna select signal changes state as the receiver switches from antenna to
antenna during the acquisition process in the antenna diversity mode. This is a
complement for ANTSEL (pin 40) for differential drive of antenna switches
