Initial Release
Clarified IP Multicast support is up to 4K groups, as it wasn’t mentioned in the data sheets
Updated Ball Signal Description Table :
•
•
Updated Section 1.4 on page 17 to indicate operation of the internal pull up/down resistors in different
modes
Clarified Section 11.1.3 on page 47 on usage of GREF_CLK
Clarified PVMODE register bit description for bits [2] & [5]
Updated ECR4Pn register description as port 9 (uplink) operates differently than the RMAC ports for MII
bi-directional clocking (bits [1:0])
I
Added Maximum Junction Temperature to Section 14.1 on page 116
Updated I/O voltage levels to use TTL spec values rather than % of Vcc
Added the following to the Feature List:
•
•
•
Added section on PHY addresses
•
Fixed error in DS on sending Ethernet Frames via 8/16-bit or serial interface.
•
Added more cross-references to available AppNotes
Added section on Stacked VLAN (Q-in-Q) and IP Multicast Switching since they weren’t really discussed in
the DS
Added more clock descriptions to “Clocks” on page 47
INT_MASK and INTP_MASK registers should state that the default register value is 0x00
Added Errata List to document
Added section on SCL clock generation
Interrupt Register was incorrectly identified as read only, should be read/write
•
Updated CPU timing diagrams to clarify timing
2
C address mapping was corrected for QOSCn registers
clarified the ball signal I/O description for Mn_TXCLK & Mn_RXCLK showing these signals are either
inputs OR outputs
clarified that M9_MTXCLK is an input only
4K jumbo frames
IEEE 802.3ad support
Reverse MII/GPSI
Clarified that they are hard-coded
The Status Bytes is sent before the frame, for both Tx and Rx
Clarified that only bit [7] is not self-clearing
