Indirect and Post-Increment Index Addressing
The syntax of the form:
[Dst_1 ++ Dst_2] = Src
is indirect, post-increment index addressing. The form is shorthand for
the following sequence.
[Dst_1] = Src ;
Dst_1 += Dst_2 ;
by Dst_2 */
where:
• is the source register. (
Src
• is the memory destination register on the left side of the
Dst_1
equation.
• is the increment index register.
Dst_2
Indirect and post-increment index addressing supports customized indi-
rect address cadence. The indirect, post-increment index version must
have separate P-registers for the input operands. If a common
for the inputs, the auto-increment feature does not work.
