S3F84B8_UM_REV 1.00 6 INSTRUCTION SET6-516.3.38 LDC/LDE — LOAD MEMORYLDC/LDE dst,srcOperation: dst srcThis instruction loads a byte from program or data memory into a working register, or vice versa.The source values remain unaffected. LDC refers to program memory, while LDE refers to datamemory. The assembler makes ‘Irr’ or ‘rr’ values even for program memory and odd for datamemory.Flags: No flags are affected.Format:Bytes Cycles Opcode(Hex)Addr Modedst src1. opc dst | src 2 10 C3 r Irr2. opc src | dst 2 10 D3 Irr r3. opc dst | src XS 3 12 E7 r XS [rr]4. opc src | dst XS 3 12 F7 XS [rr] r5. opc dst | src XL L XL H 4 14 A7 r XL [rr]6. opc src | dst XL L XL H 4 14 B7 XL [rr] r7. opc dst | 0000 DAL DAH 4 14 A7 r DA8. opc src | 0000 DAL DAH 4 14 B7 DA r9. opc dst | 0001 DAL DAH 4 14 A7 r DA10. opc src | 0001 DAL DAH 4 14 B7 DA rNOTE:1. The source (src) or working register pair [rr] for formats 5 and 6 cannot use register pair 0–1.2. For formats 3 and 4, the destination addresses ‘XS [rr]’ and source address ‘XS [rr]’ are one byte each.3. For formats 5 and 6, the destination address ‘XL [rr] and source address ‘XL [rr]’ are two bytes each.4. The DA and r source values for formats 7 and 8 address the program memory; the second set of values used in formats 9and 10 address the data memory.
