3.9.6
The cause of an interrupt related to the HDLC controllers is indicated in the ISTA register
by the ICD bit for D-channel, ICA for B-channel A and ICB for B-channel B. These bits
point to the different interrupt sources of the HDLC controllers in the ISTAD and ISTAB
registers. The individual interrupt sources of the HDLC controllers during reception and
transmission of data are explained in
Figure 86
Each interrupt source in the ISTAD and ISTAB registers can selectively be masked by
setting the corresponding bit in MASKD/MASKB to “1”.
