DWMBB/A Module Registers
Implied Vector Interrupt Destination/Diagnostic Register (AIVINTR)
AIVINTR, when used during diagnostics:
3
1 0
Diagnostic Read or Write
msb−p080−89
bits<31:0>
Name: Diagnostic Read or Write
Mnemonic: None
Type: R/W
The Diagnostic Read or Write field is used by diagnostic routines
to verify the integrity of the DWMBB/A module’s main data path
inside the DWMBB/A module gate array. When used in this manner,
diagnostics need to raise the processor’s IPL level above IPL 30 so
that, should an error occur causing the DWMBB to issue an IVINTR
transaction, an unexpected interrupt will not occur.
