Messages #16–19: These words are comparable to words #11–14, except
they are from the unselected PEs. Normally, no data reaches these
destinations, and they remain at zero.
Message #20: This displays the flag bits from the unselected PEs which
should all remain at zero.
Message #21: The test attempts to send 0x5a6a7a8a using the
rsend32
command. This word contains the low order bits of that operation.
Message #22: This is the higher order bits of the destination. All these
bits should remain zero.
Message #23: The test attempts to fetch 0x5b6b7b8b using the
rfetch32
command. This word contains the low order bits of that operation.
Message #24: This is the higher order bits of the destination. All these
bits should remain zero.
Message #25: Each cluster of 3 bits represents the state of the fflag, the
rflag and the tflag after each stage of the test.
