Programming the SICOFI
-4
With the appropriate commands, the SICOFI-4 can be programmed and verified very
flexibly via the IOM-2 Interface monitor channel.
Data transfer to the SICOFI-4 starts with a SICOFI-specific address byte (81
).
H
With the second byte 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 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 status.
A write command is followed by up to 8 bytes of data. The SICOFI-4 responds to a read
command with its IOM-2 specific address and the requested information, that is up to 8
bytes of data (see Programming Procedure, page 74).
Attention: Each byte on the monitor channel, has to be sent twice at least, according to
the IOM-2 Monitor handshake procedure. (For more information on IOM-2 specific
Monitor Channel Data Structure see appendix, page 73).
