VPD Data Register bit[19] is not read/write
VPD (Vital Product Data) is an extended capability of the ATU. Bit[19] of the VPD Data Register
(FFFF_E1BCh) is implemented as RC (read clear) instead of RW (read/write).
This is application-dependent, as VPD provides the system with information that uniquely
identifies hardware and, potentially, software elements of a system.
When the VPD feature is needed, care must be taken to mask bit[19].
No
PCI Express* Correctable Error Mask Bits
PCI Express* Correctable Error Mask (offset 114) requires both PCI/PCI-X segment A and
segment B register bits to be set to take effect.
When the mask bit is only set for one segment, the error is still reported to the host bridge.
The 80333 requires mask bits in both A- and B-segments to be set to mask the PCI Express*
correctable errors.
No
DMA CRC result is byte-reversed
The DMA CRC result value is byte-reversed.
Example CRC operation with the DMA:
Data corruption occurs when software does not take care of the byte reversal.
Software must byte reverse the CRC result after the DMA completes.
No
CRC corruption on PCI-to-local DMA transfers
CRC corruption can occur when polling DMA registers during PCI-to-local transfers. CRC
corruption happens regardless of whether the transfer data is written to memory (DMA Transfer
disable bit DCR.7, is set). Both DMA channels are affected.
CRC data corruption occurs. The DMA transfer itself is not affected by this erratum.
Use local address sources only when calculating CRC.
