Note: Flags Notation:
1 = set to 1
* = Value is a function of the result of the operation.
– = unaffected.
X = undefined.
0 = reset to 0.
Flags Register
.
The Flags register contains the status information regarding the most recent arithmetic,
logical, bit manipulation, or rotate and shift operation. The Flags register contains six bits
of status information that are set or cleared by CPU operations. Four of the bits (C, V, Z,
and S) are tested for use with conditional jump instructions. Two flags (H and D) cannot
be tested and are used for Binary-Coded Decimal (BCD) arithmetic.
The two remaining bits, User Flags (F1 and F2), are available as general-purpose status
bits. User Flags are unaffected by arithmetic operations and must be set or cleared by
instructions. The User Flags cannot be used with conditional Jumps. They are undefined at
