Header 40
The non-interleaved A-D-A-D sequences give direct read/write access to the address
range 00
together allowing data transmission on one line.
Example for a read/write access with header 40
Header 48
The interleaved A-D-A-D sequences give direct read/write access to the address range
00
registers by interleaving the data on SDX and SDR.
Example for a read/write access with header 48
Header 43
Generally, it can be used for any register access to the address range 20
sequence can have any length and is terminated by the rising edge of CS.
Example for a write access with header 43
