Interrupt Interrupt controller (ICUb)
 Interrupt vectors: 167
 External interrupts: 9 (NMI, IRQ0 to IRQ7 pins)
 Non-maskable interrupts: 6 (the NMI pin, oscillation stop detection interrupt, voltage monitoring 1
interrupt, voltage monitoring 2 interrupt, WDT interrupt, and IWDT interrupt)
 16 levels specifiable for the order of priority
External bus extension
 The external address space can be divided into four areas (CS0 to CS3), each with independent
control of access settings.
Capacity of each area: 16 Mbytes (CS0 to CS3)
A chip-select signal (CS0# to CS3#) can be output for each area.
Each area is specifiable as an 8-bit or 16-bit bus space
The data arrangement in each area is selectable as little or big endian (only for data).
Bus format: Separate bus, multiplex bus
 Wait control
 Write buffer facility
DMA DMA controller (DMACA)
 4 channels
 Three transfer modes: Normal transfer, repeat transfer, and block transfer
 Activation sources: Software trigger, external interrupts, and interrupt requests from peripheral
functions
Data transfer controller
(DTCa)
 Three transfer modes: Normal transfer, repeat transfer, and block transfer
 Activation sources: Interrupts
 Chain transfer function
I/O ports General I/O ports 145-pin/144-pin/100-pin/80-pin/69-pin/64-pin/48-pin
 I/O: 122/122/84/64/48/48/34
 Input: 1/1/1/1/1/1/1
 Pull-up resistors: 122/122/84/64/48/48/34
 Open-drain outputs: 76/76/54/44/35/35/26
 5-V tolerance:4/4/4/4/2/2*

/2
Event link controller (ELC)
 Event signals of 59 types can be directly connected to the module
 Operations of timer modules are selectable at event input
 Capable of event link operation for ports B and E
Multi-function pin controller (MPC)
 Capable of selecting input/output function from multiple pins
