PCI Lock
Exclusive access (the target resource is locked) is
accepted when the PCIC is a target
PCI Configuration Device Select
This signal is input to select the PCIC in configuration
cycles (only in normal mode).
PCI Device Select
Indicates the PCIC has decoded the address of the PCI
device as the target. When this signal is an input signal,
it indicates that the PCIC has been selected.
Interrupt D
Indicates that a PCI device is requesting PCI interrupts.
Only in host mode.
Interrupt C
Indicates that a PCI device is requesting PCI interrupts.
Only in host mode.
Interrupt B
Indicates that a PCI device is requesting PCI interrupts.
Only in host mode.
Interrupt A
Indicates that a PCI device is requesting PCI interrupts
in host mode. This signal is output so that the PCIC can
request interrupts in normal mode.
