CX11656 Functional Description

The interfaces that provide data, status, and control to and from the CX11656 include:

•

External host interface provided via the Media Independent Interface (MII) format

(described by IEEE 802.3u, Clause 22) or a General Purpose Serial Interface (GPSI)

•

Management control provided via the Management Data Interface (MDI) or the

Serial Peripheral Interface (SPI)

•

Analog Front End interface

•

LEDs indicating network status

•

Optional EEPROM interface providing a path to initialize the CX11656

•

The JTAG port implements the IEEE 1149.1 Standard Test Access Port and

Boundary Scan Architecture.
