The processor state subfield is interpreted as follows:
0000 - idle
0001 - process execution
0010 - 1111 - reserved
The interpretation of the faulted subfields is as follows:
a - not faulted 1 - faulted
The reference m:>de subfield specifies whether the references in function requests are logical or physical. In logical reference mode, function request references are relative to the
a - using physical mode 1 - using logical mode
