/** \addtogroup gmacb_module Ethernet GMACB Driver
|
|
*@{
|
|
* Implement GEMAC PHY driver, that initialize the PHY to prepare for
|
|
* Ethernet transfer.
|
|
*
|
|
* \section Usage
|
|
* -# EMAC related pins and Driver should be initialized at first.
|
|
* -# Initialize GMACB Driver instance by invoking GMACB_Init().
|
|
* -# Initialize PHY connected via GMACB_InitPhy(), PHY address is
|
|
* automatically adjusted by attempt to read.
|
|
* -# Perform PHY auto negotiate through GMACB_AutoNegotiate(), so
|
|
* connection established.
