OP_CODESEPARATOR is not used any more from what I can tell this was actually a security risk for bitcoin as per the post below.
The official info behind this would be as follows :
OP_CODESEPARATOR
OPCode = 171
Hex = 0xab
Input = Nothing
Output = Nothing
Description = All of the signature checking words will only match signatures to the data after the most recently-executed OP_CODESEPARATOR.
The post below will give some more info related to this OP code though it is no longer used as far as I can tell.

** Edit **
You can also read here some more info about it.

Hi everyone,
I am reading an article about how HASHSIG works, but i don't understand this:
Before the signature is computed, several temporary changes are made to the transaction: The signature script of the currently signed input is replaced with the public key script, excluding all occurences of OP CODESEPARATOR in it, of the referenced transaction output.
I mean why the scriptSig is replaced with the scriptPubKey?
