This bit enables and disables address translation:
A reset operation clears this bit. When translation is disabled, logical ad-

state of the E bit. Additionally, even if the E bit is set, the TC register can
affect the use of the transparent translation registers.
This bit controls the use of the supervisor root pointer register (SRP):
When the SRP is disabled, both user and supervisor accesses use the
cesses use the CRP, and supervisor accesses use the SRP.
This bit enables the use of function code lookup for searching the address
translation tables:
When function code lookup is disabled, the first level of pointer tables
within the translation table structure is indexed by the logical address field
the translation table structure is indexed by function code. In this case, the
