Direct branch addressing (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. Direct branch addressing is used for an
unconditional branch, subroutine call, or software interrupt instruction. Bits 23 to 16 of the address are
specified by the program bank register (PCB).
