REJ09B0158-0100
After device 1 has claimed and granted the bus, and transferred data, the priority is as follows:
PCIC > device 0 > device 2 > device 3 > device 1
Then, after the PCIC has claimed and granted the bus, and transferred data, the priority is changed
to:
Device 0 > device 2 > device 3 > device 1 > PCIC
After device 3 has claimed and granted the bus, and transferred data, the priority is changed to:
Device 0 > device 2 > device 1 > PCIC > device 3
In host bus bridge mode, bus parking is always controlled by the PCIC.
(5) Interrupts
•
10 interrupts are available (these signals are connected to the INTC of this LSI)
•
Interrupts are enabled/disabled and their priority levels are specified by the INTC of this LSI
•
When the PCIC operates normal mode,
INTA
output is available to the host device on the PCI
bus. The
INTA
pin is specified assert or negate by the IOCS bit in the PCICR.
Table 13.6 Interrupt Priority
Signal Interrupt
Source
Priority
PCISERR
SERR assertion detected in host bus bridge mode
High
PCIINTA
PCI interrupt A (
INTA
) detected in host bus bridge mode
PCIINTB
PCI interrupt B (
INTB
) detected in host bus bridge mode
PCIINTC
PCI interrupt C (
INTC
) detected in host bus bridge mode
PCIINTD
PCI interrupt D (
INTD
) detected in host bus bridge mode
PCIEER
Error on PCI bus occurs and reflected in PCIIR and PCIAINT. The
interrupt can be masked.
PCIPWD3
Power state transition to D3 caused by PCIPINT. The interrupt can
be masked.
PCIPWD2
Power state transition to D2 caused by PCIPINT. The interrupt can
be masked.
PCIPWD1
Power state transition to D1 caused by PCIPINT. The interrupt can
be masked.
PCIPWD0
Power state transition to D0 caused by PCIPINT. The interrupt can
be masked.
