SCHI encoding

[Dmitry N. Mikushin]

Dear all,

asfermi wiki http://code.google.com/p/asfermi/wiki/OpcodeExecution#SCHI states SM30's SCHI is

0x0010 11111111 11111111 11111111 11111111 11111111 11111111 11111111 0111

However, according to my measurements, it could be either

0x0010 11111111 11111111 11111111 11111111 11111111 11111111 11111111 0111
or
0x00100 11111111 11111111 11111111 11111111 11111111 11111111 11111111 111

Same - with SM35 - either

0x0000100 11111111 11111111 11111111 11111111 11111111 11111111 11111111 0

or
0x000010 11111111 11111111 11111111 11111111 11111111 11111111 11111111 00

It seems that no single variant could be derived from the available info. How did you make the choice to exclude one pair?

Thanks,

- D.
