Hold indication
HOLD indicates that a descriptor is the last element of a linked list
containing valid information.

Next descriptor is available in the shared memory. After checking
the HOLD bit the data management unit branches to the next
receive descriptor.
This descriptor is the last one that is available for a channel. This
means that the data section where this descriptor points to is the
last data section which is available for data storage. After
processing of descriptor has finished, the data management unit
repolls the descriptor one time to check if HOLD has already
been cleared. If HOLD is still set the corresponding receive
channel is deactivated as long as the system CPU does not
request a new activation via a ’Receive Hold Reset’ command or
forces the TE3-CHATT to branch to a new linked list via a
’Receive Abort/Branch’ command.
