DWMBB/A Module Registers
Error Summary Register (AESR)
bit<0>
Name: IBUS I/O Read Data Parity Error
Mnemonic: IBUS I/O RD PE
Type: R/W1C, 0
IBUS I/O Read Data Parity Error sets when the DWMBB/A module
detects a parity error on the IBUS when the DWMBB/B module was
loading the I/O data location during an XMI commander-initiated I/O
read or IDENT. The DWMBB issues a Read Error Response (RER) to
the commander when the error occurs during an I/O read transaction.
If the error occurs during an IDENT transaction, the DWMBB returns
the contents of the Return Vector Register (ARVR) as the vector. The
DWMBB issues an interrupt to the XMI when this bit sets if INTR I/O
RD PE (AIMR<0>) is set.
