Direct branch address (addr16)
Specify an offset explicitly for the branch destination address. The size of the offset is 16 bits, which
indicates the branch destination in the logical address space. Used for unconditional branch instructions,
subroutine call instructions and software interrupt instructions. Bit 23 to Bit16 of the address are specified
by the programming bank register (PCB).

Physical direct branch address (addr24)
Specify an offset explicitly for the branch destination address. The data length of the displacement (offset)
is 24 bits. Used for unconditional branch instructions, subroutine call instructions and software interrupt
instructions.
