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 four-oamponent access environment generated by the current context. In physical reference mode, function request references are simply 24-bit physical addresses. The reference mode subfield is interpreted as follCMs:

a - using physical mode 1 - using logical mode
