Errata Description

Applies

to Mask

ED1

Description (revised 11/9/98):

XY memory data move does not work properly under one of the following

two situations:

1. The X-memory move destination is internal I/O and the Y-memory

move source is a register used as destination in the previous adjacent move

from non Y-memory

2. The Y-memory move destination is a register used as source in the next

adjacent move to non Y-memory.

Here are examples of the two cases (where x:(r1) is a peripheral):

Example 1:

move #$12,y0

move x0,x:(r7) y0,y:(r3) (while x:(r7) is a peripheral).

Example 2:

mac

x1,y0,a x1,x:(r1)+

y:(r6)+,y0

move

y0,y1

Any of the following alternatives can be used:

Separate these two consecutive moves by any other instruction.

Split XY Data Move to two moves.

Pertains to: DSP56300 Family Manual, Section B-5 "Peripheral pipeline

restrictions.
