9.9 Fast Opto-Isolated Serial Interface Mode Signal Description and
Configuration
Fast Opto-Isolated Serial Interface Mode provides a method of communicating with an
external device over USB using 4 wires that can have opto-isolators in their path, thus
providing galvanic isolation between systems. If either channel A or channel B are
enabled in fast opto-isolated serial mode then the pins on channel B are switched to the
fast serial interface configuration. The I/O interface for fast serial mode is always on
channel B, even if both channels are being used in this mode. An address bit is used to
determine the source or destination channel of the data. It therefore makes sense to
always use at least channel B or both for fast serial mode, but not A own its own.
When either Channel B or Both Channel A and B are configured in Fast Opto-Isolated
Serial Interface mode following IO signal lines are configured as follows:
Pin#
13
12
11
10
Fast Opto-Isolated serial interface mode is enabled in the external EEPROM.

Description
Fast serial data input
Clock input into the chip to clock data in or out. The
external device has to provide a clock signal or nothing
will change on the interface pins. This gives the
external device full control over the interface. It is
designed to be half duplex so that data is only
transferred in one direction at a time.
