Data Sheet
interleaving the data on SDX and SDR.
Example for a read/write access with header 48
Header 4A
The A-D-D-D sequences give a fast read-/write-only access to the address range 00
6F
The starting address (wradr, rdadr) is autoincremented after every data byte. The
sequence can have any length and is terminated by the rising edge of CS.
Example for a write access with header 4A
Example for a read access with header 4A
Header 43
This mode (header 43
address (rdadr, wradr) in the range between 00h and 1F gives access to the current
FIFO location 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.
