I know little more
about these instructions other than their operation codes and their

Operation code (hex) Mnemonic
-------------------- --------
23 testlds
24 testlde
25 testldd
26 teststs
27 testste
28 teststd

2) What do these instructions do? How do they affect registers and
what are the cycle times?
You mean the load and store Status Register, E Register and D Register?
Nah ... you don't want to know :-) (tease!). Maybe you should ask an
INMOS FAE... maybe he doesn't know. Maybe you should read my book when
