PCI CONFIGURATION REGISTERS

BUILT-IN SELF-TEST REGISTER (BIST)
Register Name:
Built-in Self-Test
Address Offset:
0Fh
Power-up value:
00h
Boot-load:
External nvRAM/EPROM
offset 04Fh
Attribute:
D7, D5-0 Read Only, D6 as
PCI bus write only
Size:
8 bits
The Built-In Self-Test (BIST) register permits the
implementation of custom, user-specific diagnostics.
This register has four fields as depicted in Figure 10.
Bit 7, when set signifies that this device supports a
built-in self test. When bit 7 is set, writing a 1 to bit 6
will commence the self test. In actuality, writing a 1 to
bit 6 produces an interrupt to the Add-On interface.
Bit 6 will remain set until cleared by a write operation
to this register from the Add-On bus interface. When
bit 6 is reset it is interpreted as completion of the self-
test and an error is indicated by a non-zero value for
the completion code (bits 3:0).

Bit
Description
7
BIST Capable. This bit indicates that the Add-On device supports a built-in self-test when a one is
returned. A zero should be returned if this self test feature is not desired. This field is read only
from the PCI interface.
6
Start BIST. Writing a 1 to this bit indicates that the self-test should commence. This bit can only be
written when bit 7 is a 1. When bit 6 becomes set, an interrupt is issued to the Add-On interface. Other
than through the reset pin, Bit 6 can only be cleared by a write to this element from the Add-On bus
interface as outlined in Section 6.5. The PCI bus specification requires that this bit be cleared within
2 seconds after being set, or the device will be failed.
5:4
Reserved. These bits are reserved. This field will always return zeros.
3:0
Completion Code. This field provides a method for detailing a device-specific error. It is considered
valid when the Start BIST field (bit 6) changes from 1 to 0. An all-zero value for the completion code
indicates successful completion.
