Release Notes for Tri-Speed Ethernet MAC

• Added support for ECP3 devices
• New GSR implementation
• Correct issues found at UNH compliance testing
• LM32 wrapper updated to support SGMII Easy connect mode

2.7

2008-09

• Selectable interfaces to PHY
  • Classic Tri-Speed MAC with G/MII
  • Gigabit MAC with GMII - Has no internal Tx EBR and does not require any PLLs in the top design, it is also smaller in size tha the CLASSIC_TSMAC or SGMII_TSMAC
  • SGMII Easy Connect with GMII for ECP2/M and SC/M devices - Offers seamless connectivity to the Lattice Gigabit Ethernet PCS IP.  Has an 8-bit GMII interface and uses clock enables.  A single 125Mhz clock can be used for all 3 speed modes.
• Now handles "non-standard" preambles.
• TX_RX_CTL register bit-6 has been changed from the previously non functional Dis_rtry to "Drop_control".  When set, it will drop Rx pause frames inside the MAC, instead of allowing them to be presented to the client interface.
• Fix to the LatticeMico32 wrapper to correct the Rx clock generation when in 10/100 mode.
