The cause of an interrupt related to the HDLC controller is indicated by the HDLC bit in
the ISTA register. This bit points at the different interrupt sources of the HDLC controller
part in the ISTAH register. The individual interrupt sources of the HDLC controller during
reception and transmission of data are explained in chapter 3.2.1 or 3.3.1 respectively.
