Header 41
This sequence allows in front of the A-D-D-D write access a non-interleaved A-D-A-D
read access. This mode is useful for reading status information before writing to the
HDLC XFIFO. The termination condition of the read access is the reception of the wradr.
The sequence can have any length and is terminated by the rising edge of CS.
Example for a read/write access with header 41
Header 49
This sequence allows in front of the A-D-D-D write access an interleaved A-D-A-D read
access. This mode is useful for reading status information before writing to the HDLC
XFIFO. The termination condition of the read access is the reception of the wradr. The
sequence can have any length and is terminated by the rising edge of the CS line.

3.2.3
Special events in the device are indicated by means of a single interrupt output, which
requests the host to read status information from the device or transfer data from/to the
device.
Since only one interrupt request pin (INT) is provided, the cause of an interrupt must be
determined by the host reading the interrupt status registers of the device.
The structure of the interrupt status registers is shown in
