Description
1 = Force CIM to send jam pattern.
0 = Normal operation mode
1 = Disable carrier integrity monitor function.
0 = Enable carrier integrity monitor function.
Default is 0.
1 = Disable 10BASE-T SEQ testing.
0 = Enable 10BASE-T SEQ testing, which generates a COL
pulse following the completion of a packet transmission.
1 = Enable 10BASE-T normal loop back.
0 = Disable 10BASE-T normal loop back.
1 = Disable auto polarity detection/correction.
0 = Enable auto polarity detection/correction.
When Reg16.5 is set to 0, this bit sets to 1 if Reverse Polarity
is detected on the media, otherwise it is zero. When Reg16.5
is set to 1, writing a one to the bit reverses the polarity of the
transmitter.
Note: The reverse polarity is detected either through 8
inverted NLP or through a burst of inverted FLP.
