APPENDIX B Instructions
●
Physical direct branch addressing (addr24)
Specify an offset explicitly for the branch destination address. The size of the offset is 24 bits. Physical
direct branch addressing is used for unconditional branch, subroutine call, or software interrupt instruction.
Figure B.3-4 Example of Direct Branch Addressing (addr24)
●
I/O direct addressing (io)
Specify an 8-bit offset explicitly for the memory address in an operand. The I/O address space in the
physical address space from 000000
H
to 0000FF
H
is accessed regardless of the data bank register (DTB)
and direct page register (DPR). A bank select prefix for bank addressing is invalid if specified before an
instruction using I/O direct addressing.
