Subject: AMCC 405EX Rev D PVR
Date: Mon, 21 Dec 2009 09:37:36 -0600 [thread overview]
Message-ID: <eabe9a7b0912210737l7cace1acka2220755566bdbfc@mail.gmail.com> (raw)
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
