Instruction code
3.1.3 Table indirect addressing
[Function]
Table contents (branch destination address) of the particular location to be addressed by the lower-5-bit
immediate data of an instruction code from bit 1 to bit 5 are transferred to the program counter (PC) and
branched.
When the “CALLT [addr5]” instruction is executed, table indirect addressing is performed. Executing this
instruction enables the value to be branched to all memory spaces referencing the address stored in the
memory table of 40H to 7FH.
