IPGData
Inter-Packet Gap (IPG) Data.
The step is 100ns (1 bit-time). The default value is 96
decimal (9.6
s). Note that the IPG during jam varies
between 1 bit-time and 128 bit-times.

DataBlind
Data Blinder.
DataBlind is the inhibit time. The time the GT-48001A
port does not look at the line to decide to transmit.The
range is 0 to 96 in 100ns increments. The default is 64
decimal (6.4us).
