Initial Release
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 10.1.3 on page 44 on usage of REF_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 13.1 on page 112
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 serial interface.
•
Added more cross-references to available AppNotes
Added more clock descriptions to “Clocks” on page 44
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
•
Added section “Default Switch Configuration and Initialization Sequence” on page 20
Removed reference to direct register INDEX_REG1 (address 0x1) from SSI diagrams, as not applicable
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
