User manual
10.8.2 Example PHY Devices
Support for IEEE 802.3/clause 31 flow control is implemented in the flow control block.
Receive flow control frames are automatically handled by the MAC. Transmit flow control
frames can be initiated by software. In half duplex mode, the flow control module will
generate back pressure by sending out continuous preamble only, interrupted by pauses
to prevent the jabber limit from being exceeded.
The Ethernet block has a standard Reduced Media Independent Interface (RMII) to
connect to an external Ethernet PHY chip. Registers in the PHY chip are accessed via the
AHB interface through the serial management connection of the MIIM bus, typically
operating at 2.5 MHz.
Some examples of compatible PHY devices are shown in
