3.3.3 Table indirect addressing
[Function]
Table indirect addressing specifies a table address in the CALLT table area (0080H to 00BFH) with the 5-bit
immediate data in the instruction word, stores the contents at that table address and the next address in the program
counter (PC) as 16-bit data, and specifies the program address. Table indirect addressing is applied only for CALLT
instructions.
In the RL78 microcontrollers, branching is enabled only to the 64 KB space from 00000H to 0FFFFH.
