Header 40
The non-interleaved A-D-A-D sequence gives direct read/write access to the complete
address range and can have any length. In this mode SDX and SDR can be connected
together allowing data transmission on one line.
Example for a read/write access with header 40
Header 48
The interleaved A-D-A-D sequence gives direct read/write access to the complete
address range and can have any length. This mode allows a time optimized access to
the registers by interleaving the data on SDX and SDR (SDR and SDX must not be
connected together).
Example for a read/write access with header 48
Header 43
This mode can be used for a fast access to the HDLC FIFO data. Any address (rdadr,
wradr) in the range 00
selected by an internal pointer which is automatically incremented with every data byte
following the first address byte. The sequence can have any length and is terminated by
the rising edge of CS.
