With the appropriate commands, the IOM-2 – SICOFI-2 can be programmed and
verified very flexibly via the IOM-2 Interface monitor channel.
Data transfer to the IOM-2 – SICOFI-2 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
IOM-2 – SICOFI-2 feature control facilities, SOP, COP and XOP commands contain
additional information (e.g. number of subsequent bytes) for programming (write) and
verifying (read) the IOM-2 – SICOFI-2 status.
A write command is followed by up to 8 bytes of data. The IOM-2 – SICOFI-2 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 18
).
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 64
).

Types of Monitor Bytes
The 8-bit Monitor 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 IOM-2 – SICOFI-2 commands which are selected by bit 3 and 4 as shown below.
SOP
STATUS OPERATION:
IOM-2 – SICOFI-2 status
setting/monitoring
XOP
EXTENDED OPERATIO:
C/I channel configuration/evaluation
COP
COEFFICIENT OPERATION:
filter coefficient setting/monitoring
