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.
PCI bus clock input of up to 33.34MHz.
Address data lines [31:0] (bidirectional).
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).
Initialization device select (active high).
Device select to the XR17D158 (active low).
Device interrupt from XR17D158 (open drain, active low).
Parity is even across AD[31:0] and C/BE[3:0]# (bidirectional, active high).
Data Parity error indicator, except for Special Cycle transactions (active low).
Optional in bus target application.
System error indicator, Address parity or Data parity during Special Cycle
transactions (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).
