With the appropriate commands, the SICOFI-4- C can be programmed and verified very
flexibly via the -Controller interface.
With the first byte received via DIN, one of 3 different types of commands (SOP, XOP
and COP) is selected. Each of those can be used as a write or read command. Due to
the extended SICOFI-4- C feature control facilities, SOP, COP and XOP commands
contain additional information (e.g. number of subsequent bytes) for programming
(write) and verifying (read) the SICOFI-4- C status.
A write command is followed by up to 8 bytes of data. The SICOFI-4- C responds to a
read command with its specific identification and the requested information, that is up to
8 bytes of data.
3.1
The 8-bit bytes have to be interpreted as either commands or status information stored
in Configuration Registers or the Coefficient-RAM. There are three different types of
SICOFI -4- C commands which are selected by bit 3 and 4 as shown below.
