RSSISAMPLE

[0..127]

RSSI sample result. The value of this register is read as a

positive value while the actual received signal strength is a

negative value. Actual received signal strength is therefore

as follows: received signal strength = -A dBm.

RW DATAWHITEIV

Data whitening initial value. Bit 6 is hardwired to '1', writing

'0' to it has no effect, and it will always be read back and

used by the device as '1'.

Bit 0 corresponds to Position 6 of the LSFR, Bit 1 to Position

5, etc.
