a)

RSSI_ACQ input signal rising edge will trigger RSSI sampling, and falling edge will trigger internal digital RSSI information written to I2C.

It is recommended that host shall not trigger RSSI_ACQ input again until RSSI data is valid in I2C from previous RSSI trigger.

b)

RSSI DDM working range is between -12 to -32 dBm. RSSI DDM accuracy is better than +/- 3dB for input power levels between -15 to -32

dBm, the accuracy reduces to +/- 5 dBm for -12 dBm to -15 dBm. If the data pattern is at least 2^7-1 or longer, a minimum average of 8

times is strongly recommended to maintain the RSSI reading accuracy.
