PTEST
MOTOROLA
Level field—Specifies the depth to which the translation table should be searched.
FC field—Function code of address to test.
R/W field—Specifies whether the A-bit should be updated for a read or a write.
A-Register field—Specifies the address register in which to load the last descriptor
1—Read
0—Write
address.
1DDDD — Function code is specified as four bits DDDD.
01RRR — Function code is contained in CPU data register RRR.
00000 — Function code is contained in CPU source function code register.
00001 — Function code is contained in CPU destination function code
1RRR — Return the last descriptor address to address register RRR.
When the PTEST instruction specifies a level of zero, the A-
register field must be 0000. Otherwise, an F-line exception is
generated.
0xxx — Do not return the last descriptor address to an address register.
