Data Sheet
Header 48
The interleaved A-D-A-D sequences give direct read/write access to the address range
00
have any length. This mode allows a time optimized access to the registers by
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 incremented automatically after every data byte.
The sequence can have any length and is terminated by the rising edge of CS.
