EM Selection Switch
The EM selection switch on SmartRF05BB controls a multiplexer on the board that allows either a
connected RF SoC EM or
an MSP430 add
-
on board to access all four LEDs on the evaluation board.
The limitation was caused by the particular pin
-
out on the RF evaluation modules that needed to be
backwards compatible with other boards and test equipment.

EM Selection Switch (P8)
The switch will both affect the operation of the LEDs and Button 1.
NB: The
EM Selection
switch shall be placed in position SoC/TRX when the CC2530EM is used with
SmartRF05BB.
