PCI Bus Interrupt B: This output
indicates a programmable interrupt
request generated from any of a number
of card actions. Although there is no
specific mapping requirement for
connecting interrupt lines from the
OZ6933 to the system, a common use is
to connect this pin to the system PCI bus
INTB# signal.
IRQSER/SOUT#/IRQ5: In PC/PCI Serial
Interrupt Signaling mode, this pin is the
serial interrupt output, SOUT#. In PC/Way
mode, this pin is the IRQ serializer pin to
the interrupt controller. In the parallel ISA
mode, this pin is the ISA IRQ5
IRQ7/SIN#/B_VPP_PGM: In PC/PCI
Serial Input Signaling mode, this pin is the
serial interrupt input, SIN#. In the parallel
ISA mode, this pin is the ISA IRQ7. This
pin also can be configured as parallel
power control pin B_VPP_PGM
Grant: This signal indicates that access
to the bus has been granted.
Request: This signal indicates to the
arbiter that the OZ6933 requests use of
the bus.
PCI LOCK#: This signal is used by a PCI
master to perform a locked transaction to
a target memory. LOCK# is used to
prevent more than one master from using
a particular system resource.
PCI Bus VCC: These pins must be
connected to a 3.3-volt power supply. The
PCI bus interface pin outputs listed in this
table (Table 2-1) will operate at the
voltage applied to these pins, independent
of the voltage applied to other OZ6933 pin
groups.

memory cycles, this output chooses
between attribute and common
memory. During I/O cycles for non-DMA
transfers, this signal is active (low).
During ATA mode, this signal is always
inactive. For DMA cycles on the
OZ6933 to a DMA-capable card, -REG
is inactive during I/O cycles to indicate
DACK to the PCMCIA card.
CardBus Command Byte Enable: In
CardBus mode, this pin is the CCBE3#.
