Why does this piece of assembly not work?

Catcus Blip

Hello all,

Can you tell mw why this piece of code:

LDMDB   R13, {R0 - LR}^
NOP
MOVS    PC, LR // hand over control to task

does not update registers R13 and R14 (but does update R0 - R12)? The write back operator (!) is indeed not present (i.e.

LDMDB R13!...

but this does not compile) which may explain R13, but why isn't then R14 being updated? Even if I try to separately extract R13, R14 from by buffer (pointed by R13) it does not work. Any ideas?
