I have observed an odd behavior in the latest 405EX revision parts (Rev D).

Upon first power up on our custom board,
the 405EX Rev D shows a value of 0x12911470 in the PVR register.

After a reset, the 405EX Rev D shows the correct value of 0x12911475
in the PVR register.

The 405EX Rev C part had a steady 0x1291147F on first power up on the
same board.

Has anyone seen this ?

Is a wider reset pulse is required for the Rev D 405EX ?

Thanks for any feedback,

Lee
