If the dsp value is positive

2.4 Special Instruction Addressing

If the dsp value is negative

• If the jump length specifier (.length)
is (.S)...
the base address plus the value
indicated by displacement (dsp)—
added not including the sign bits—
constitutes the effective address.

This addressing can be used in JMP
instruction.

• If the jump length specifier (.length) is
(.B) or (.W)...
the base address plus the value indicated
by displacement (dsp)—added including
the sign bits—constitutes the effective
address.

However, if the addition resulted in
exceeding 00000

16

- FFFFF

16

, the bits

above bit 21 are ignored, and the address
returns to 00000

16

or FFFFF

16

.

This addressing can be used in JMP and
JSR instructions.

*1 The base address is the (start address of instr 2).

*2 The base address varies with each instruction.

If the specifier is (.B), -128
