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

I
Bus clock input of up to 33MHz.
Address data lines [31:0] (bidirectional).
AD31-AD0
IO
FRAME#
I
Bus transaction cycle frame (active low). It indicates the begining and duration
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 XR17C158 (active low).
Device interrupt from XR17C158 (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.
