An example with the same programming sequence as before, using the IOM-2 interface
is presented here to show the differences between the microcontroller interface and the
IOM-2 interface.

Because the SLICOFI-2S has an open command structure, no fixed command length is
given. The IOM-2 handshake protocol allows for an infinite length of a data stream;
therefore, the host must terminate the data transfer by sending an end-of-message
signal (EOM) to the SLICOFI-2S. The SLICOFI-2S will abort the transfer only if the host
tries to write or read beyond the allowed maximum offsets given by the different types of
commands. Each transfer must start with the SLICOFI-2S-specific IOM-2 Address (81
and must end with an EOM of the handshake bits. Appending a command immediately
to its predecessor without an EOM in between is not allowed.
When reading interrupt registers, SLICOFI-2S stops the transfer after the fourth register
in IOM-2 mode. This is to prevent some host chips from reading 16 bytes because they
cannot terminate the transfer after n bytes.
