The last revision of the datasheet (revision 2550) introduced two errors that have now been corrected:
–
–
Additional minor datasheet clarifications and corrections.
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 422).
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.
The LQFP pin diagrams and pin tables were missing the comparator positive and negative input
pins.
The base address was listed incorrectly in the FMPRE0 and FMPPE0 register bit diagrams.
Ball C1: Changed PE7 to NC
Ball C2: Changed PE6 to NC
Ball D2: Changed PE5 to NC
Ball D1: Changed PE4 to NC
Ball F1: Changed PD7 to NC
Ball F2: Changed PD6 to NC
Ball E2: Changed PD5 to NC
Ball E1: Changed PD4 to NC
