The 108-Ball BGA pin diagram and pin tables had an error. The following signals were erroneously
indicated as available and have now been changed to a No Connect (NC):
–
–
As noted in the PCN, three of the nine Ethernet LED configuration options are no longer supported: TX
Activity (0x2), RX Activity (0x3), and Collision (0x4). These values for the LED0 and LED1 bit fields in
the MR23 register are now marked as reserved.
As noted in the PCN, the option to provide VDD25 power from external sources was removed. Use the
LDO output as the source of VDD25 input.
As noted in the PCN, pin 41 (ball K3 on the BGA package) was renamed from GNDPHY to ERBIAS. A
12.4-kΩ resistor should be connected between ERBIAS and ground to accommodate future device
revisions (see “Functional Description” on page 354).
Additional minor datasheet clarifications and corrections.
Corrected resistor value in ERBIAS signal description.
Additional minor datasheet clarifications and corrections.
Added note on clearing interrupts to Interrupts chapter.
Added Power Architecture diagram to System Control chapter.
Additional minor datasheet clarifications and corrections.
Ball C1: Changed PE7 to NC
Ball C2: Changed PE6 to NC
