13. PCI Controller (PCIC)
Subsequently, after the PCIC requires the bus and transfer data and the request is permitted, the
priority changes as follows:
Device 0 > device 2 > device 3 > device 1 > PCIC
Then, after the device 3 requires the bus and transfer data and the request is permitted, the priority
changes as follows:
Device 0 > device 2 > device 1 > PCIC > device 3
(4)
• The PCIC has 10 interrupts (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 in normal mode, INTA output is available as an interrupt to the host
