Vector Addressing (#vct)
Specify vector data in an operand to indicate the branch destination address. There are two sizes for vector
numbers: 4 bits and 8 bits. Vector addressing is used for a subroutine call or software interrupt instruction.
Figure B.3-11 Example of Vector Addressing (#vct)
Note:
When the program bank register (PCB) is FF
H
, the vector area overlaps the vector area of INT #vct8
(#0 to #7). Use vector addressing carefully (see Table B.3-2 ).
