Instructions manual for CEPR96 / MRUC20 M97.10.01 SYNTAX Hexadecimal : Mnemonic : EXECUTION INDIRECT TRANSFERT OF DATA INDIRECT DOUBLE ADDRESSING - BLOC FORMAT ACCU. MEMORY ADdeb ADfin COMMENTS Transfert a bloc of successives data that begining address (DAdy) is contain at the address DAdeb to a memory zone that it begining address (ADdx) is contain at the address ADdeb and it end address (ADdz) is contain at the address ADfin. SYMBOLS DEFINITION LIMITS EXAMPLE Transfert of the bloc of data that it begining address is contain at the address 60H to a zone define by the begining address that it address is contain at the address 05H and by the last address that it address is contain at the address 18H. Hexadecimal: 01 50 10 08 05 18 60 04 Mnemonic: MOV.BI,5,18H,60H. NC 50 NL 08 ADdeb ADfin DAdeb 04 MOV.BI,ADdeb,ADfin,DAdeb. ADdx ADdz INDRECT DOUBLE ADDRESSING PAGE 16 ACCU. MEMORY DAdeb DAdy ADdeb pointer on the starting address of the destination zone ADfin pointer on the last address of the destination zone DAdeb pointer on the starting address of the source zone 50H MOV.BI 0 to FFH 0 to FFH 0 to FFH
SYNTAX Hexadecimal : Mnémonic : EXECUTION MOVE IMMEDIATE DATA TO EXTENDED MEMORY COMMENTS The extended memory zone is define by a begining address (A016) and the number of bytes to write (N). If there is only 1 data, the same data is write everywhere in the defined zone. If the instruction contain less data (DVn) than the defined zone, the result will be unpredictable (the missing data will be the old data contain before the transfert). SYMBOLS DEFINITION LIMITS EXAMPLE Ex. 1: Transfert the values 1,2,3 from address 0 of the accumulator. Before After NC 72 NL NB N0 A016 DV0...DVN 04 LMOV,N0,A016,DV0,..DVN Extended Memory A016 A016+1 A016+N N Lenght of the zone to write A016 First address of the zone to write DVN Immediate data to write PAGE 17 Instructions manual for CEPR96 / MRUC20 M97.10.01 IMMEDIATE DATA DV0 DV1 DVn Note : If N = 0 , the lenght of the zone to write is fixed to 256 bytes.
