Preliminary
5.1.3
The microcontroller interface consists of four lines: CS, DCLK, DIN and DOUT.

There are two different command types. Reset commands have just one byte. Read/
write commands have two command bytes with the address offset information located in
the second byte.
A write command consists of two command bytes and the following data bytes. The first
command byte determines whether the command is read or write, how the command
field is to be used, and which DuSLIC channel (A or B) is written. The second command
byte contains the address offset.
A read command consists of two command bytes written to DIN. After the second
command byte is applied to DIN, a dump-byte consisting of ‘1’s is written to DOUT. Data
transfer starts with the first byte following the ‘dump-byte’.
