Header 41
This sequence (header 41
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 (header 49
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.
