Description
•
LD HL,(mn):
Loads L with the data whose address is mn and loads the H with the data
whose address is mn plus 1.
•
LD HL,(HL+d):
Loads L with the data whose address is the data in HL plus a displacement
d. Then loads H with the data whose address is the data in HL plus a displacement d plus 1.
•
LD HL,(IX+d):
Loads L with the data whose address is the data in IX plus a displacement
d. Then loads H with the data whose address is the data in IX plus a displacement d plus 1.
•
LD HL,(IY+d):
Loads L with the data whose address is the data in IY plus a displacement
d. Then loads H with the data whose address is the data in IY plus a displacement d plus 1.
