Description (revised 11/ 9/ 98):
XY memory data move does not work properly if 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 OR 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
This is not a bug, but a documentation update. Any of the following
alternatives can be used:

instruction.
Separate these two consecutive moves by any other
b.
Description (added 10/ 09/ 1997):
Split XY Data Move to two moves.

BL pin timings T198 and T199 in the Data Sheet are changed,
improving the arbitration latency:
T198 is 5 ns (max), T199 is 0 ns (min).
This is not a bug, but a documentation update.
