All incoming data bytes are stored in the RFIFO. If the FIFO is full an RFO interrupt is
asserted (EXMR.SRA = ’0’).
Note: In the extended transparent mode the EXMR register has to be set to ’xxx00000’

All interrupt sources from the ISTAH register are combined (ORed) to a single HDLC
controller interrupt signal hint. Each of the interrupt sources can individually be masked
in the MASKH register. A masked interrupt is not indicated in the ISTAH register but
remains internally stored and pending until the interrupt is unmasked and read by the
host.
The HDLC controller interrupts XDU and XMR have special impact on the internal
functions. E.g. the transmitter of the HDLC controller is locked if a data underrun
condition occurs and the ISTAH.XDU is not read (the interrupt can only be read if
unmasked), same applies for XMR.
