(32) CSMA control register 3 (BBCSMACON3)
This register controls the CSMA-CA operation.
The BEMIN bit is used to set the macMinBE value. (Initial value is 3H.)
Set the smaller value for the BEMIN bit than the BEMAX bit setting value.
Set value other than 0H to these bits to perform CCA.
The BBCSMACON3 register consists of 8 bits and can be accessed (serial interface communication) in 8 bit
unit.
Reset signal generation sets this register to 03H.
