Description
Low power
consumption
Low power
consumption facilities
ï· Module stop function
ï· Four low power consumption modes
Sleep mode, all-module clock stop mode, software standby mode, and deep software
standby mode
ï· Battery backup function
Interrupt
Interrupt controller
(ICUb)
ï· Peripheral function interrupts: 187 sources
ï· External interrupts: 16 (pins IRQ0 to IRQ15)
ï· Software interrupts: One source
ï· Non-maskable interrupts: 6 sources
ï· Sixteen levels specifiable for the order of priority
External bus extension
ï· The external address space can be divided into nine areas (CS0 to CS7, SDCS), each
with independent control of access settings.
Capacity of each area: 16 Mbytes (CS0 to CS7), 128 Mbytes (SDCS)
A chip-select signal (CS0# to CS7#, SDCS#) 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).
ï· SDRAM interface connectable
ï· Bus format: Separate bus, multiplex bus
ï· Wait control
ï· Write buffer facility
DMA
DMA controller
(DMAC)
ï· 4 channels
ï· Three transfer modes: Normal transfer, repeat transfer, and block transfer
ï· Activation sources: Software trigger, external interrupts, and interrupt requests from
peripheral functions
EXDMA controller
(EXDMACa)
ï· 2 channels
ï· Four transfer modes: Normal transfer, repeat transfer, block transfer, and cluster transfer
ï· Single-address transfer enabled with the EDAKn signal
ï· Capable of direct data transfer to TFT LCD panels
ï· Activation sources: Software trigger, external DMA requests (EDREQn), and interrupt
requests from peripheral functions
Data transfer
controller (DTCa)
ï· Three transfer modes: Normal transfer, repeat transfer, and block transfer
ï· Activation sources: External interrupts and interrupt requests from peripheral functions
