+ contents and issues no coherence
+ requests and responds as if the line
+ were not present. Cache contents cannot

+ when 0 external notification is

+ cause the processor to deviate
+ from its normal execution and

+ ordered from the longest running tests up
+ to the shortest running tests with bit 0
+ controlling the longest running test. PAL
+ may not implement all 47-bits of the
+ test_control word. PAL communicates if a
+ bit provides control by placing a zero in
+ that bit. If a bit provides no control,
+ PAL will place a one in it. PAL will have
+ two sets of test_control bits for the two
+ phases of the processor self-test. PAL
+ provides information about implemented
+ test_control bits at the hand-off from PAL
+ to SAL for the firmware recovery check.
+ These test_control bits provide control
+ for phase one of processor self-test. It
+ also provides this information via the PAL
+ procedure call PAL_TEST_INFO for both the
+ phase one and phase two processor tests
+ depending on which information the caller
+ is requesting. PAL interprets these bits
+ as input parameters on two occasions. The
+ first time is when SAL passes control back
+ to PAL after the firmware recovery check.
+ The second time is when a call to
+ PAL_TEST_PROC is made. When PAL interprets
+ these bits it will only interpret
+ implemented test_control bits and will
+ ignore the values located in the
+ unimplemented test_control bits. PAL
+ interprets the implemented bits such that
+ if a bit contains a zero, this indicates
+ to run the test. If a bit contains a one,
+ this indicates to PAL to skip the test. If
+ the cs bit indicates that control is not
+ available, the test_control bits will be
