4 PIN DESCRIPTION
The following tables provide a brief description of each pin on the W9961CF. The following signal
type definitions are used in these descriptions:
I
Input pin
IU
Input pin with internal pull-up resistor
B
Bi-directional input/output pin
O
Output pin
TS
Tri-State output pin
STS
Sustained Tri-State pin. Must drive it high for at least one PCI clock before letting it float.
A
Analog pin
P
Power supply pin
G
Ground pin
#
Active low

Description
AD[31:0]
1, 2, 4, 5, 7-
10, 13-20,
35-42, 45-52
B
Multiplexed System Address and Data Bus. The address phase
is the clock cycle in which FRAME# is asserted. Data is
transferred during those clocks where both IRDY# and TRDY#
are asserted.
C/BE[3:0]#
11, 22, 34, 44
I
Multiplexed Bus Command and Byte Enables. During the
address phase of a transaction, C/BE[3:0]# define the bus
command. During the data phase C/BE[3:0]# are used as Byte
Enables.
PAR
33
TS
Parity. It is even parity across AD31-AD0 and C/BE[3:0]#.
FRAME#
23
I
Cycle Frame. Asserted to indicate a bus transaction is
beginning.
TRDY#
26
STS
Target Ready. A data phase is completed on any clock both
TRDY# and IRDY# are sampled asserted.
IRDY#
25
I
Initiator Ready. A data phase is completed on any clock both
IRDY# and TRDY# are sampled asserted.
