DWMBB/B Module Registers
Vector Offset Register (BVOR)
Vector Offset Register (BVOR)
The Vector Offset Register contains a value that is concatenated with the
VAXBI device-supplied vector, if bits<13:9> of the VAXBI-supplied vector are
equal to zero.

Name: DWMBB/B Vector Offset Register
Mnemonic: VOR
Type: R/W, 0
The Vector Offset Register field is a 7-bit register loaded by software
upon system initialization. The BVOR contains a value that is
concatenated with the VAXBI device-supplied vector, providing that
bits <13:9> of the VAXBI-supplied vector are equal to zero, ensuring
that multiple DWMBB/VAXBIs with the same devices on each bus will
have a unique entry point into the SCB.
