CHAPTER 3 CPU ARCHITECTURE3.3.2 Immediate addressing[Function]Immediate data in the instruction word is transferred to the program counter (PC) and branched.This function is carried out when the CALL !addr16 and BR !addr16 instructions are executed.CALL !addr16 and BR !addr16 instructions can be used to branch to all the memory spaces.[Illustration]In case of CALL !addr16 and BR !addr16 instructions7 0CALL or BRLow addr.High addr.PC15 8 7054User’s Manual U14801EJ3V1<strong>UD</strong>
CHAPTER 3 CPU ARCHITECTURE3.3.3 Table indirect addressing[Function]The table contents (branch destination address) of the particular location to be addressed by the immediate dataof an instruction code from bit 1 to bit 5 are transferred to the program counter (PC) and branched.Table indirect addressing is carried out when the CALLT [addr5] instruction is executed. This instruction can beused to branch to all the memory spaces according to the address stored in the memory table 40H to 7FH.[Illustration]7 6 5 1 0Instruction code0 1ta4–0015 8 7 6 5 1 0Effective address 0 0 0 0 0 0 0 0 0 107 Memory (Table) 0Low addr.Effective address + 1High addr.15 8 70PC3.3.4 Register addressing[Function]The register pair (AX) contents to be specified with an instruction word are transferred to the program counter(PC) and branched.This function is carried out when the BR AX instruction is executed.[Illustration]7 0 70rpAX15 8 70PCUser’s Manual U14801EJ3V1<strong>UD</strong> 55
