Condition Formula
OV = 1 Overflow
OV = 0 No overflow
Carry
CY = 1
Lower (Less than)
No carry
CY = 0
Not lower (Greater than or equal)
Zero
Z = 1
Equal
Not zero
Z = 0
Not equal
(CY or Z) = 1 Not higher (Less than or equal)
(CY or Z) = 0 Higher (Greater than)
S = 1 Negative
S = 0 Positive
— Always (Unconditional)
SAT = 1 Saturated
(S xor OV) = 1 Less than signed
(S xor OV) = 0 Greater than or equal signed
((S xor OV) or Z) = 1 Less than or equal signed
((S xor OV) or Z) = 0 Greater than signed
