S3F84B8_UM_REV 1.00 6 INSTRUCTION SET6-576.3.44 LDW — LOAD WORDLDW dst,srcOperation: dst srcThe contents of source (word) are loaded into the destination. The contents of source remainunaffected.Flags: No flags are affected.Format:Bytes Cycles Opcode(Hex)Addr Modedst srcopc src dst 3 8 C4 RR RR8 C5 RR IRopc dst src 4 8 C6 RR IMLExamples: Given R4 = 06H, R5 = 1CH, R6 = 05H, R7 = 02H, register 00H = 1AH,register 01H = 02H, register 02H = 03H, and register 03H = 0FH:LDW RR6,RR4 R6 = 06H, R7 = 1CH, R4 = 06H, R5 = 1CHLDW 00H,02H Register 00H = 03H, register 01H = 0FH,register 02H = 03H, register 03H = 0FHLDW RR2,@R7 R2 = 03H, R3 = 0FH,LDW 04H,@01H Register 04H = 03H, register 05H = 0FHLDW RR6,#1234H R6 = 12H, R7 = 34HLDW 02H,#0FEDH Register 02H = 0FH, register 03H = 0EDHIn the second example, note that the statement “LDW 00H,02H” loads the contents of sourceword 02H, 03H into the destination word 00H, 01H. This leaves the value 03H in general register00H and the value 0FH in register 01H.Other examples show how to use the LDW instruction with various addressing modes andformats.
