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.
input power range between -12 to -30dBm and the accuracy reduces to +/-5dB for input power
range between -10 to -12dBm. 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.
