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 or BR !addr16 or CALLF !addr11 instruction is executed.
CALL !addr16 and BR !addr16 instructions can be branched to the entire memory space. The CALLF !addr11
instruction is branched to the 0800H to 0FFFH area.
