(13) CCA level threshold setting register (BBCCAVTH)
This register is used to set the threshold level to judge the CCA. It judges as busy for the CCA value which
is the value set to this register or greater.The value is set as 2’s complement. The setting unit is dBm (ex.
”19EH” is ”- 98dBm”).
The BBCCAVTH register is set by the serial interface in 8-bit units.
Reset signal generation sets this register to 0100H.
