17. In Section 4.1, Multi-Purpose Pins Functional Summary, on page 51:
• Changed all references to MPP[0] and MPP[11] from GPI to GPIO.
• Changed the MPP[6] row in the table to remove the 0x0 option.
• Added the following bullet at the end of the section, after the tables: When TWSI serial ROM initialization is enabled,
MPP[8] and MPP[9] wake up as TWSI data and clock pins, respectively.
• Revised the description of SYSRST_OUTn.
• Added a bullet: Pin MPP[6] wakes up after reset in 0x1 mode (SYSRST_OUTn).
18. In Table 27, Ethernet Ports Pins Multiplexing, on page 57, added a new configuration option for the Gigabit Ethernet
ports: Port 0 MII/MMII, port 1 RGMII.
19. In Section 4.3, TSMP (TS Multiplexing Pins) on MPP, on page 59, added to the description of the TSMP pins.

32. In the Table 36, Recommended Operating Conditions, on page 77:
• Added values for VDD_CPU.
• Added VHV and revised the voltage for the SATA and XTAL AVDD parameters.
• For the 3.3V interfaces, revised the minimum value to 3.15V and the maximum value to 3.45V (+/-5%).
• Revised the description of the VDD_GE_A/VDD_GE_B row, to show that RGMII can also operate with a voltage of
3.3V.
• Revised the values for PEX_AVDD to minimum 1.7V, typical 1.8V, and maximum 1.9V.

34. In Table 38, Current Consumption, on page 80
• Revised values for Core, Embedded CPU, SATA, PCI Express and USB parameters.
• Changed all occurrences of VDD_CPU to VDD.
• Revised the interface RGMII 1.8V interface to RGMII 1.8V or 3.3V interface.
• Revised the notes following the table to remove reference to the trace length or resistance.
35. Deleted Section 8.5.2 REF_CLK_XIN 2.5V (CMOS) DC Electrical Specifications and added pin REF_CLK_XIN to
Section 8.5.2, RGMII, SMI and REF_CLK_XIN 1.8V (CMOS) DC Electrical Specifications, on page 82, since the
power rail for the REF_CLK_XIN pin was changed from 2.5V to 1.8V.
