ONFIGURING THE
AC4868-250
The AC4868-250 can be configured using the CC Configuration Commands. The CC Commands can be
issued using either Hardware or Software Configuration. To use Hardware Configuration, pin 17 of a
transceiver must be asserted Low. Software Configuration can be used by entering AT Command Mode
before issuing the CC Commands.

AT Commands
The AT Command mode implemented in the AC4868-250 creates a virtual version of the Command/Data pin.
The “Enter AT Command Mode” Command asserts this virtual pin Low (to signify Command Mode) and the
“Exit AT Command Mode” Command asserts this virtual pin High (to signify Data). Once this pin has been
asserted Low, all On-the-Fly CC Commands documented in the manual are supported.
