CS is used to start a serial access to the SICOFI-2/4-TE registers and Coefficient-RAM.
identification, the specified n data bytes (contents of configuration registers, or contents
of the CRAM) will follow on DOUT.
2.4
The internal configuration registers, the signaling interface, and the Coefficient-RAM
(CRAM) of the SICOFI-2/4-TE are programmable via a serial -Controller interface.
The -Controller interface consists of four lines: CS, DCLK, DIN and DOUT:
Following a falling edge of CS, the first eight bits received on DIN specify the command.
Subsequent data bytes (number depends on command) are stored in the selected
configuration registers or the selected part of the Coefficient-RAM.

Example for a Write Access, with Two Data Bytes Transferred
If the first eight bits received via DIN specify a read-command, the SICOFI-2/4 TE will
start a response via DOUT with its specific address byte (81
