Description
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
OZ6833 to the system, a common use is
to connect this pin to the system PCI bus
INTB# signal.
SOUT#/IRQSER: 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.
SIN#: In PC/PCI Serial Input Signaling
mode, this pin is the serial interrupt input,
SIN#.
Grant: This signal indicates that access
to the bus has been granted.
Request: This signal indicates to the
arbiter that the OZ6833 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 can be
connected to either a 3.3- or 5-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 OZ6833 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
OZ6833 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#.
