Receive and transmit channel are enabled (default)
Receive channel is disabled
Transmit channel is disabled
not used
In halfduplex mode the pump would transfer idle bits in the direction that is currently not in
use, so the corresponding receive or transmit channel can be selectively disabled to reduce
the interrupt load for not valid data.
For all other pump modes except halfduplex mode, HDMC must be set to its default value 00.

The fillword functionality can be used to transmit "1" or "0" or any other 8 bit value without
continuous message transfer between host and ISAR.
