If the condition cc is true then HL is set to one. Otherwise, HL is reset to zero.

Condition Code	Flag Bit Value	Description
NZ	Z=0	True when the Z flag has not been set
Z	Z=1	True when the Z flag has been set
NC	C=0	True when the C flag has not been set
C	C=1	True when the C flag has been set
GT	(Z or (S xor V))=0	True when Z is 0 and L/V and S are either both 1 or both 0.
LT	(S xor V)=1	True when either S is 1 or L/V is 1.
GTU	((C=0) and (Z=0))=1	True when C and Z are both 0.
V	L/V=1	True when the L/V flag is set: there is overflow.
