Function Description
Interrupt
(source)
Interrupt
controller
(INTC)
•
Thirteen external interrupt pins (NMI, and IRQ11 to IRQ0)
•
56 internal interrupt sources
•
Two interrupt control modes (specified by the interrupt control
register)
•
Eight priority orders specifiable (by setting the interrupt priority
register)
•
Independent vector addresses
DMA Data
transfer
controller
(DTC)
•
Allows DMA transfer over 45 channels (number of DTC
activation sources)
•
Activated by interrupt sources (chain transfer enabled)
•
Three transfer modes (normal transfer, repeat transfer, block
transfer)
•
Short-address mode or full-address mode selectable
•
16-Mbyte external address space
External bus
extension
Bus
controller
(BSC)
•
The external address space can be divided into eight areas,
each of which is independently controllable
Chip-select signals (
CS0
to
CA7
) can be output
Access in two or three states can be selected for each area
Program wait cycles can be inserted
The period of
CS
assertion can be extended
Idle cycles can be inserted
•
Bus arbitration function (arbitrates bus mastership among the
internal CPU and DTC, and external bus masters)
