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, see
Table 19 on page 48
.
Bus clock input of up to 33.34MHz at 5V.
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.
Bus Command/Byte Enable [3:0] (active low). This line is multiplexed for bus
Command during the address phase and Byte Enables during the data
phase.
Initiator Ready (active low). During a write, it indicates that valid data is
present on data bus. During a read, it indicates the master is ready to accept
data.
Target Ready (active low).
Target request to stop current transaction (active low). 5
Initialization device select (active high).
Device select to the XR17C154 (active low).
Device interrupt from XR17C154 (open drain, active low).
Parity is even across AD[31:0] and C/BE[3:0]# (bidirectional, active high).
Parity error indicator to host (active low). Optional in bus target application.
System error indicator to host (open drain, active low). Optional in bus target
application.

UART channel 0 Transmit Data or infrared transmit data. Normal TXD output
idles HIGH while infrared TXD output idles LOW.
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].
UART channel 0 Request to Send or general purpose output (active low).
UART channel 0 Clear to Send or general purpose input (active low).
UART channel 0 Data Terminal Ready or general purpose output (active low).
UART channel 0 Data Set Ready or general purpose input (active low).
UART channel 0 Carrier Detect or general purpose input (active low).
UART channel 0 Ring Indicator or general purpose input (active low).
UART channel 1 Transmit Data or infrared transmit data. Normal TXD output
idles HIGH while infrared TXD output idles LOW.
