CS used for Chip Select Output for Serial Devices which have a 4 wire interface like the
AST45DB011 and also serial data on two wire devices like the 24C08.
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.
