Status Port Page 2 - 13
Note
Whenever the board is
reset, the host operations
should wait a minimum
of five seconds before
testing the RDY bit. If,
after the delay, the RDY
bit is not set to one, the
value in the Self-test
Code field of the Status
Port will indicate the
failing test. The RF3880
will not accept
commands if this occurs.
The Status Port fields during power-up or reset, have these meanings:
STC Self-test Code - This bit works in conjunction with bits 2 through 7, to
indicate the self-test currently executing.
RDY Ready - This bit indicates when the adapter is ready to accept commands
after a reset has completed.
0 ⇒ No command can be accepted.
1 ⇒ Ready to accept a command.
Self-test Code - The values of these bits change as self-test progresses. As
self-test begins and progresses, the values are updated to the code of the test
currently executing.
See below for a table of Self-test Codes.
Status Port
Error Codes
If one of the self-tests does not properly complete, its test number will be left
in the Self-test Code byte. The following table describes the test numbers:
Code Description
00H or FDH
The onboard processor is not working; it cannot access firmware EPROM; cannot
access the Status Port.
04H
Static RAM error. All words of static RAM are written with FFFFH, then zero.
This test is not exhaustive.
0CH
Firmware CRC error. The calculated CRC for odd and even EPROMs does not
match the value stored in EPROM.
80H SCSI PSI Address/Counter registers not masked to WORD boundaries.
84H SCSI PSI Address/Counter registers no masked to DWORD boundaries.
88H Value Miscompare errors of SCSI PSI R/W registers in Manual Load mode.
8CH Value Miscompare errors of SCSI PSI R/W registers in Auto Load mode.
90H VME PSI Address/Counter registers not masked to WORD boundaries.
94H VME PSI Address/Counter registers not masked to DWORD boundaries.
98H Value Miscompare errors of VME PSI R/W registers in Manual Load mode.
9CH Value Miscompare errors of VME PSI R/W registers in Auto Load mode.
A8H
SCSI termination power fuse is blown, but termination power is still present at the
SCSI connector.
ACH
SCSI termination power fuse is blown and termination power is not available at
the SCSI connector.
B0H Value Miscompare error of QLogic Fast SCSI chips R/W registers.
B4H QLogic Fast SCSI chip did not generate a reset interrupt.
B8H QLogic Fast SCSI chip registers not zeroed after reset.
BCH SCSI bus hung, waiting for reset from QLogic Fast SCSI chip. Could be cabling.
D0H Video RAM buffer error.
E5H The onboard processor failed the accumulator test.
E8H The onboard processor failed the store instruction test.
E9H The onboard processor failed the shift instruction test.
ECH The onboard processor failed the compare instruction test.
EDH The onboard processor failed the jump instruction test.
