PIC32MX6/7 family with embedded Ethernet
controller – PHY support
This document briefly explains how to add a new PHY to the MCHP TCPIP-BSD stack.
Note: The same approach applies to the MCHP TCPIP stack.

How to add a new PHY
Microchip provides a PHY interface library that is being used as part of the MAC driver for the
TCPIP stack.
The basic concepts behind this PHY library are:
The functions that the current TCPIP stack MAC driver uses for communicating and configuring
the external PHY are prototyped in
and implemented in the
To add support for a new PHY you have to add the implementation for the
following
“..install path\Microchip\Include\TCPIP-BSD\eth_phy.h”):
•
1. Communication to the PHY is done using MIIM interface. For access to the external PHY
2. All PHYs support a standard set of registers with well known functionality. (As part of the
3. Few functions that are vendor specific have to be added for particular PHY’s.
Support for other PHY's will be added in the future.
The PIC32MX6-7 families with embedded Ethernet controller have support for external
MII/RMII connected PHY’s. Currently we support:
registers over the MIIM interface the communication functions provided by the Ethernet
Controller Peripheral Library are used (“..path\Microchip\MPLAB
C32\pic32mx\include\peripheral\eth.h”).
