S5 TNB instruction question

[uptown47]

Hi all,

The TNB instruction in S5 transfers bytes from one location to another but I'm not sure which is the Src and which the Destination addresses.

If I had the following:
L (pointer to DB10.byte 0)
L (pointer to DB99.byte 0)
TNB 50

Are the 50 bytes going from DB 10 to DB 99 or is it going from DB 99 to DB 10 ??

I've looked at the manual but it says that the src and destination are Accu 2 which can't be right can it?!?

See manual attached...

 

[L D[AR2P#0.0]]

From another manual:

Brilliant stuff!

Many thanks. Sods law that the bit of the manual I needed had a typo!!
