controller (DTC)
Interrupt controller
(INTC)
Specification
⢠256 Kbytes/384 Kbytes/512 Kbytes (see the list in product lineup)
⢠12 Kbytes/16 Kbytes (see the list in product lineup)
⢠Address space: A maximum 64 Mbytes for each of two areas (CS0 and
CS1)
⢠8-bit external bus
⢠The following features settable for each area independently
⯠Number of access wait cycles
⯠Idle wait cycle insertion
⯠Supports SRAM
⢠Outputs a chip select signal according to the target area
⢠Data transfer activated by an on-chip peripheral module interrupt can
be done independently of the CPU transfer.
⢠Transfer mode selectable for each interrupt source (transfer mode is
specified in memory)
⢠Multiple data transfer enabled for one activation source
⢠Various transfer modes
Normal mode, repeat mode, or block transfer mode can be selected.
⢠Data transfer size can be specified as byte, word, or longword
⢠The interrupt that activated the DTC can be issued to the CPU.
A CPU interrupt can be requested after one data transfer completion.
⢠A CPU interrupt can be requested after all specified data transfer
completion.
⢠Five external interrupt pins (NMI and IRQ3 to IRQ0)
⢠On-chip peripheral interrupts: Priority level set for each module
⢠Vector addresses: A vector address for each interrupt source
