(15) Transmit/receive mode register 4 (BBTXRXMODE4)
This register sets the various types of the RF transmit/receive mode.
The CCA interrupt select bit can be used to select the CCA interrupt source between the time upon
completion of the CCA sequence and the time upon completion of the CSMA-CS sequence.
The INT output polarity switch bit can be used to select the interrupt polarity of the interrupt output from the
INTOUT pin.
Automatic receive with timeout after transmit enable bit enables automatic receive with timeout after
transmit by automatic receive switch mode 0 enable bit. Byte receive interrupt and receive timeout interrupt
can be switched by receive timeout interrupt switch bit.
The BBTXRXMODE4 register is set by the serial interface in 8-bit units.
Reset signal generation sets this register to 01H.
