AT7911E

5.

Control Interface

The AT7911E can be configured/controled through two interfaces:

• HOCI interface

• Link control interface

5.1

HOCI interface

The HOst Control Interface is especialy designed for access to internal AT6911E registers by a

local controller (µController, FPGA etc.).

The detailed description of this operation mode can be found in the section 5.4 of the

'SMCS332SpW User Manual'.

5.2

Link control interface

Link control is the feature of the AT7911E that allows the control of the AT7911E not only via

HOCI but via one of the three links. This allows to use the AT7911E in systems without a local

controller. Since the HOCI is no longer used in this operation mode, it is instead available as a

set of general purpose I/O (GPIO) lines.

The detailed description of this operation mode can be found in the section 5.4 of the

'SMCS332SpW User Manual'.
