2.4 Special Instruction Addressing
Chapter 2 Addressing Modes
dsp:20[A0]
dsp:20[A1]
[A1A0]
20-bit absolute
abs20
Address register relative with 20-bit displacement
32-bit address register indirect
The address indicated by the displacement
(dsp) plus the content of the address
register (A0/A1)—added without the sign
bits—is the effective address for the
operation.
However, if the addition results in a value
exceeding FFFFF
ignored, and the address returns to
00000
This addressing mode can be used with
the LDE, STE, JMPI, and JSRI instructions.
Valid addressing mode and instruction
combinations are as follows.
dsp: 20[A0]
dsp: 20[A1]
The value indicated by abs20 is the
effective address for the operation.
The effective address range is 00000
FFFFF
This addressing mode can be used with
the LDE, STE, JSR, and JMP instructions.
The address indicated by the 32
concatenated bits of the address
registers (A0 and A1) is the effective
address for the operation.
However, if the concatenated register
value exceeds FFFFF
above are ignored.
This addressing mode can be used
with the LDE and STE instructions.
