DWMBB/B Module Registers
Control and Status Register (BCSR)
VAXBI BAD sets when BI BAD L deasserts to indicate that all VAXBI
nodes have passed self-test, except for the DWMBB/B module, where it
means that the BIIC passed its internal self-test.
bit<3>
Name: Reserved
Mnemonic: None
Type: RO, 0
Reserved; must be zero.
bit<2>
Name: VAXBI Interlock Read Failed Mask
Mnemonic: None
Type: R/W, 0
VAXBI Interlock Read Failed Mask, when set, causes the DWMBB to
generate an error interrupt request if VAXBI Interlock Read Failed
(BESR<2>) is set.
bit<1>
Name: VAXBI Power-Up LED
Mnemonic: None
Type: R/W, 0
VAXBI Power-Up LED is set by the XMI boot processor executing
power-up code when the DWMBB power-up completes without error.
When the VAXBI Power-Up LED bit sets, the self-test LED lights on
the DWMBB/B module.
The VAXBI Power-Up LED bit has no effect on the operation of the
self-test LED on the DWMBB/A module.
bit<0>
Name: IBUS Parity Error Interrupt Mask
Mnemonic: None
Type: R/W, 0
IBUS Parity Error Interrupt Mask, when set, causes the DWMBB
to generate an error interrupt request if DWMBB/B-Detected IBUS
Parity Error (BESR<0>) is set.
