so the possible branching range is –126 to +128 bytes (–63 to +64 words) or –32766 to +32768
bytes (–16383 to +16384 words) from the branch instruction. The resulting value should be an
even number.
Memory Indirect—@@aa:8
This mode can be used by the JMP and JSR instructions. The instruction code contains an 8-bit
absolute address specifying a memory operand. This memory operand contains a branch address.
The memory operand is accessed by longword access. The first byte of the memory operand is
ignored, generating a 24-bit branch address. Figure 2.8 shows how to specify branch address for in
memory indirect mode. The upper bits of the absolute address are all assumed to be 0, so the
address range is 0 to 255 (H'0000 to H'00FF).
Note that the first part of the address range is also the exception vector area.
