3.3.2 Immediate addressing
80
[Function]
[Illustration]
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. However, before
branching to a memory bank that is not set by the memory bank select register (BANK), change the setting of
the memory bank by using BANK.
The CALLF !addr11 instruction is branched to the 0800H to 0FFFH area.
