Rabbit 2000 - 7.2 Rabbit Oscillators and Clocks

74 Rabbit 2000/3000 Microprocessor
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.
