Type Strength Description
ALT_INTA/ AF7 AF11 O 8 mA
PCI
Active LOW Alternate Interrupt A
indicates that the PCI Function is
requesting service from its host device
driver. ALT_INTA/ is an open drain
signal. The interrupt request routing
mode bits, bits [9:8] in the Host Interrupt
Mask register, controls the routing of
interrupt signals to INTA/ and/or
ALT_INTA/. Refer to the
Host Interrupt
Mask register, page 4-41 , for more
detailed information.
BZVDD,
BZRESET AF4, AE5 AD11, AF10 I N/A BZVDD is the VDD for the BZ controller
(PVT control block for PCI) and is
equivalent to PVT2 in the LSI53C1030
chip.
BZRESET is the reset input for the for
BZ controller and is equivalent to PVT1
in the LSI53C1030 chip.
Connect a 49.9
Ω
, 1% resistor between
BZVDD and BZRESET.
