PIN DESCRIPTIONS
NAME
PIN #
TYPE
DESCRIPTION
PCI LOCAL BUS INTERFACE
RST#
134
I
PCI Bus reset input (active low). It resets the PCI local bus configuration
space registers, device configuration registers and UART channel registers
to the default condition.
CLK
135
I
PCI Bus clock input of up to 33.34MHz.
AD31-AD25,
AD24,
AD23-AD16,
AD15-AD8,
AD7-AD0
138-144,
1,
6-13
26-33
37-44
IO
Address data lines [31:0] (bidirectional).
FRAME#
15
I
Bus transaction cycle frame (active low). It indicates the beginning and dura-
tion of an access.
C/BE3#-
C/BE0#
2,14,25,36
I
Bus Command/Byte Enable [3:0] (active low). This line is multiplexed for bus
Command during the address phase and Byte Enable during the data phase.
IRDY#
16
I
Initiator Ready (active low). During a write, it indicates valid data is present
on data bus. During a read, it indicates the master is ready to accept data.
TRDY#
17
O
Target Ready (active low).
STOP#
21
O
Target request to stop current transaction (active low). 5
IDSEL
3
I
Initialization device select (active high).
DEVSEL#
18
O
Device select to the XR17D154 (active low).
INTA#
133
OD
Device interrupt from XR17D154 (open drain, active low).
PAR
24
IO
Parity is even across AD[31:0] and C/BE[3:0]# (bidirectional, active high).
PERR#
22
O
Parity error indicator to host (active low). Optional in bus target application.
SERR#
23
OD
System error indicator to host (open drain, active low). Optional in bus target
application.
MODEM OR SERIAL I/O INTERFACE
TX0
125
O
UART channel 0 Transmit Data or infrared transmit data. Normal TXD output
idles HIGH while infrared TXD output idles LOW.
RX0
132
I
UART channel 0 Receive Data or infrared receive data. Normal RXD input
idles HIGH. The infrared pulses typically idle LOW but can be inverted inter-
nally prior the decoder by FCTR[4].
RTS0#
127
O
UART channel 0 Request to Send or general purpose output (active low).
CTS0#
131
I
UART channel 0 Clear to Send or general purpose input (active low).
DTR0#
126
O
UART channel 0 Data Terminal Ready or general purpose output (active
low).
DSR0#
130
I
UART channel 0 Data Set Ready or general purpose input (active low).
CD0#
129
I
UART channel 0 Carrier Detect or general purpose input (active low).
RI0#
128
I
UART channel 0 Ring Indicator or general purpose input (active low).
