RSSI_OUT
Analog
Output
RSSI Output
Output RSSI (= Received Signal Strength
Indication) voltage. Connect ground via a
capacitor. This IC has another RSSI signal
for digital processing.
At no use, connect ground via a capacitor.

Input
Address Setting (In EEPROM Mode)
Set a start address to read memory data.
Notice:
Do not supply higher voltage than the level
of COM_VDD. (For example, in the case
of too low / no power supply.) That causes
overcurrent at this pin, as the ESD
protection elements insertion between the
pin and the voltage source.
