System Error: This output is driven
active LOW to indicate an address parity
error.
Parity: This pin generates PCI parity and
ensures even parity across AD[31:0] and
C/BE[3:0]#. During the address phase,
PAR is valid after one clock. With data
phases, PAR is stable one clock after a
write or read transaction.
PCI Clock: This input provides timing for
all transactions on the PCI bus to and from
the OZ6933. All PCI bus signals, except
RST#, are sampled and driven on the
rising edge of PCI_CLK. This input can be
operated at frequencies from 0 to 33MHz.
Device Reset: This input is used to
initialize all registers and internal logic to
their reset states and place most OZ6933
pins in a HIGH-impedance state.
Ring Indicate Out: This pin is Ring
Indicate when the following occurs while
O2 Mode Control B Register (index 2Eh)
bit 7 is set to 1:
1) Power Control (Index+02h) bit 7 set
to 1
2) Interrupt and General Control
(Index+03h) bit 7 set to 1
3) PCI O2Micro Control 2 (Offset: D4h)
bit X = 0
PCI Clock Run Request: This signal is
used by the central resource to request
permission to stop the PCI clock or to slow
it down, and the OZ6933 responds
accordingly. To enable the CLKRUN#
signal, you need to enable ExCA register
3B bit[3:2].
Power Management Event: A power
management event is the process by
which the OZ6933 can request a change
of its power consumption state. Usually, a
PME occurs during a request to change
from a power saving state to the fully
operational state.
Socket B Activity: This signal indicates
that there is any activity on the socket B
read/write access. Refer to PCI
Configuration Register 90h.
PCI Bus Interrupt A: 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
INTA# signal.
