(66) ANT0 read register (BBANT0RD)
This register is used to store the RSSI value when the ANTSELOUT0 pin output is at the high level.
The reading value is corresponding save bank specified by receive data save bank select bit.
The value is set as 2’s complement. The setting unit is dBm (ex. ”19EH” is ”-98dBm”).
BBANT0RD register is set via serial interface in 8-bit units.
Reset signal generation sets this register to 0100H.

Caution “0” is always read for bits 9 to 15.
(67) ANT1 read register (BBANT1RD)
This register is used to store the RSSI value when the ANTSELOUT1 pin output is at the high level.
The reading value is corresponding save bank specified by receive data save bank select bit.
The value is set as 2’s complement. The setting unit is dBm (ex. ”19EH” is ”-98dBm”).
BBANT1RD register is set via serial interface in 8-bit units.
