Description
PCI Configuration Device Select
This signal is input to the PCI device to select
configuration cycles (only for normal mode).
PCI Device Select
Indicates the device driving this signal has decoded its
address as the target. As an input, this signal indicates
that a device has been selected.
Interrupts D, C, and B
Indicate that a PCI device is requesting an interrupt.
Only these signals are available in host bus bridge
mode.
Interrupt A
Indicates that a PCI device is requesting an interrupt
(input) in host bus bridge mode. This signal is used to
request an interrupt (output: O/D) in normal mode.
PCI Bus Request
Available only in host bus bridge mode.
PCI Bus Grant
Available only in host bus bridge mode.
PCI Bus Request
Functions as an input or an output in host bus bridge
mode and as an output in normal mode.
PCI Bus Grant
Functions as an input or an output in host bus bridge
mode and as an input in normal mode.
PCI System Error
PCI Parity Error
PCI reset output (only for host bus bridge mode)
PCI Operating Mode Select
Low: PCI normal mode in which the PCIC operates as
a PCI bridge on the PCICLK
High: PCI host bus bridge mode in which the PCIC
operates as a PCI bridge on the PCICLK
