(25) Back off period register (BBBOFFPROD)
This register is used to control the back off period.
The back off period auto random enable bit is used to automatically generate the random value with setting
the value set to the back off period bit as an initial value, and to set the back off period value in the CSMA-
CA circuit.
Set the random value to the back-off period register 2, and then set “1” to the back off period auto random
enable bit of the back off period register.
The BBBOFFPROD register consists of 8 bits and can be accessed (serial interface communication) in 8 bit
unit.
Reset signal generation clears this register to 00H.
