(35) Receive level threshold setting register (BBLVLVTH)
This register is used to set the threshold value of the receive level.
The value is set as 2's complement The setting unit is dBm (ex. ”19EH” is ”-98dBm”).
Reception is done for level beyond the setting value.
The minimum setting value is recommended for the data rate and value of RSSI/CCA result register
(BBRSSICCARSLT). For details, see 18.4.4 (5) RSSI/CCA result register (BBRSSICCARSLT).
The BBLVLVTH register is set by the serial interface in 8-bit units.
Reset signal generation sets this register to 0100H.
