In Run Mode Slave, the receiver is able to continuously scan for incoming data streams.
Detection and validation of a wake-up criterion are not performed.
The transparent data stream can be processed externally by the Application Controller
(see
Run Mode Slave is entered by setting SFR CMC0 bits MSEL to 0 and SLRXEN to 1.
Configurations are switched via SFR bit group MCS in the CMC0 register. The RF
channel in use can be selected in the x_CHCFG register, the frequency selection is
defined by SFRs x_PLLINTCy, x_PLLFRAC0Cy, x_PLLFRAC1Cy, x_PLLFRAC2Cy,
where x = A, B, C or D and y = 1, 2 or 3.
The configuration may be changed only in SLEEP or in HOLD Mode before returning to
the previously selected operation mode. This is necessary to restart the state machine
