First Transmit Descriptor Address points to the beginning of the transmit data
chaining list.
This descriptor is only interpreted with a fast transmit abort or a transmit jump
or a transmit initialization command. It is read but ignored with any other
transmit channel command.
Individual Transmit Buffer Size; for undisturbed transmission an on-chip
transmit buffer with a total size of 64 long words stores the data before
formatting and transmitting. The individual buffer size specifies the part of the
on chip transmit buffer allocated to the channel. This allows a variable data
buffer size if NITBS = 0, ITBS has to be set to 0 also; it is then read but
ignored. (see Chapter 2.3).
