Talk:Condition Code Register

In the Motorola M68HC11 microcontroller's condition code registers, there are 8 bytes,one each for S, X, H, I, N, Z, V, and C.

The H bit represents a carry from bit 3 during an addition operation. The N bit represents the state of the most significant bit (aka MSB)of a result. The Z bit is the set when all bits of the result are zeros. The V bit indicates if a 2's complement overflow has occurred from an operation. The C bit indicates if a carry from an addition or borrow has occurred from a subtraction.

Merge?

It seems wasteful to have articles on condition code registers, status register, and flag byte. Should at least this one be merged with status register, or merge all three? --Mike Van Emmerik 02:28, 1 March 2006 (UTC)
