• Bit 7 – RX_CRC_VALID
Refer to section 6.3.5.
• Bit 6:5 – RND_VALUE
Refer to section 9.2.2.
• Bit 4:0 – RSSI
The result of the automated RSSI measurement is stored in register bits RSSI. The
value is updated at time intervals according to Table 6-24 in any receive state. RSSI is
a number between 0 and 28, representing the received signal strength with a resolution
of about 3 dB.
