Description
Interrupt
Interrupt controller
(ICUA)
 Peripheral function interrupts: 293 sources
 External interrupts: 16 (pins IRQ0 to IRQ15)
 Software interrupts: 2 sources
 Non-maskable interrupts: 7 sources
 Sixteen levels specifiable for the order of priority
 Method of interrupt source selection:
The interrupt vectors consist of 256 vectors (128 sources are fixed. The remaining 128
vectors are selected from among the other 156 sources.)
External bus extension
 The external address space can be divided into eight areas (CS0 to CS7), each with
independent control of access settings.
Capacity of each area: 16 Mbytes (CS0 to CS7)
A chip-select signal (CS0# to CS7#) can be output for each area.
Each area is specifiable as an 8-, 16-, or 32-bit bus space.
The data arrangement in each area is selectable as little or big endian (only for data).
 SDRAM interface connectable
 Bus format: Separate bus, multiplex bus
 Wait control
 Write buffer facility
DMA
DMA controller
(DMACAa)
 8 channels
 Three transfer modes: Normal transfer, repeat transfer, and block transfer
 Request sources: Software trigger, external interrupts, and interrupt requests from
peripheral functions
EXDMA controller
(EXDMACa)
 2 channels
Four transfer modes: Normal transfer, repeat transfer, block transfer, and cluster
transfer
 Single-address transfer enabled with the EDACKn signal
 Request sources: Software trigger, external DMA requests (EDREQn), and interrupt
requests from peripheral functions
Data transfer controller  Three transfer modes: Normal transfer, repeat transfer, and block transfer
(DTCa)
 Request sources: External interrupts and interrupt requests from peripheral functions
I/O ports
Programmable I/O ports
 I/O ports for the 177-pin TFLGA, 176-pin LFBGA, and 176-pin LFQFP
I/O pins: 127
Input pin: 1
Pull-up resistors: 127
Open-drain outputs: 127
5-V tolerance: 19
 I/O ports for the 145-pin TFLGA and 144-pin LFQFP
I/O pins: 111
Input pin: 1
Pull-up resistors: 111
Open-drain outputs: 111
5-V tolerance: 18
 I/O ports for the 100-pin TFLGA and 100-pin LFQFP
I/O pins: 78
Input pin: 1
Pull-up resistors: 78
Open-drain outputs: 78
5-V tolerance: 17
Event link controller (ELC)
 Event signals such as interrupt request signals can be interlinked with the operation of
functions such as timer counting, eliminating the need for intervention by the CPU to
control the functions.
 119 internal event signals can be freely combined for interlinked operation with
connected functions.
 Event signals from peripheral modules can be used to change the states of output pins
(of ports B and E).
 Changes in the states of pins (of ports B and E) being used as inputs can be interlinked
with the operation of peripheral modules.
