CHAPTER 3 ADDRESSING

3.1.3 Table Indirect Addressing
[Function]
Table contents (branch destination address) of the particular location, addressed by the low-order-5-bit
immediate data of an instruction code from bit 1 to bit 5, are transferred to the program counter (PC) and
branched.
Table indirect addressing is performed when the CALLT [addr5] instruction is executed. This instruction
references the address stored in the memory table (40H to 7FH) and can be used to branch to any address
within the memory spaces.
