Replaced “Parity support to detect internal memory failures during

runtime” by “Parity support to detect runtime failures for other internal

memories”.

Section 2.34: Clock and reset system: corrected a typo error in bullet

“PLL2 programmable dithered PLL, dedicated for the 125 MHz clock

of the Gigabit Ethernet MACs”

Section 2.4: Multiport DDR controller (MPMC): Split bullet “Exclusive

and locked accesses support weighted round-robin arbitration

scheme support to ensure high memory bandwidth utilization” into 2

separate ones.

Section 2.9: Giga/Fast Ethernet port (GMAC): Deleted the phrase:

“note that this timing information is shared between the two Giga

Ethernet controllers to provide highest precision in “bridging”

operations”, since only one Giga Ethernet controller is available.

Section 2.10: PCI Express controller (PCIe): updated the

introduction.

Section 2.26: I2S digital audio ports (I2S): removed bullet “External

SCLK gating and enable signal”, as SCLK is an internal signal.

Section 2.27: S/PDIF digital audio port: removed bullet “Can detect

IEC-61937 compressed data” and related footnote from the ‘input’

features group.

Section 2.20: LCD display controller (CLCD): replaced bullet

“Programmable pixel clock frequency up to bus clock frequency” by

“Programmable pixel clock frequency up to 148MHz (1080p

resolution)”.

Section 2.22: Video decoder (VDEC):

– Updated the bullet “H.263 profile and level” as follows:

- added the image size limitation to Profile 0

- deleted sub-bullet “Sorenson Spark” and added it as a separate

bullet

– Split bullet “VP6, VP7 and VP8, versions 0-3” into two bullets:

- VP6 and VP7, versions 0-3

- VP8 version 2 (WebM)

– Added sub-bullet “Baseline interleaved” to bullet “JPEG, all

common sampling formats”.

–Bullet “Input image size”: added limitation to standalone mode.

–Bullet “Image cropping / digital zoom”: added limitation “Usable

only for JPEG or stand-alone mode”.

Section 2.29: Cryptographic co-processor (C3):

– Removed numerical IDs (such as ID: 0x00001020).

– Removed Channel 7: empty bullet.

Section 2.32: General purpose timers (GPT): corrected “8-bit timer

clock prescaler” to “4-bit timer clock prescaler” in the first two bullets.

Section 2.19: General purpose I/O (GPIO/XGPIO): updated the first

paragraph of introduction.

Section 2.22: Video decoder (VDEC):

– Changed “Supported video profiles” to “Supported video codecs”.

– Updated bullet “H.264 profile and level”.
