Features
Clock pulse generator
(CPG/PLL)
• On-chip clock pulse generator (maximum operating frequency: 80 MHz)
• Independent generation of CPU system clock and peripheral clock for peripheral modules
• On-chip clock-multiplication PLL circuit (×8)
Interrupt controller (INTC)
• Internal clock frequency range: 5 to 10 MHz
• Nine external interrupt pins (NMI, IRQ0 to IRQ7)
• 123 internal interrupt sources
(ATU-II × 75, SCI × 20, DMAC × 4, A/D × 5, WDT × 1, UBC × 1, CMT × 2, HCAN-II × 8, H-
UDI × 1, SSU* × 6 )
• 16 programmable priority levels
User break controller
(UBC)
• Requests an interrupt when the CPU or DMAC generates a bus cycle with specified
conditions (interrupt can also be masked)
• Trigger pulse output (UBCTRG) on break condition
⎯ Selection of trigger pulse width (φ ×1, ×4, ×8, ×16)
• Simplifies configuration of an on-chip debugger
Bus state controller (BSC) • Supports external memory access (SRAM and ROM directly connectable)
⎯ 8/16-bit bus space
• 3.3 V bus interface
• 16 MB address space divided into four areas, with the following parameters settable for
each area:
⎯ Bus size (8 or 16 bits)
⎯ Number of wait cycles
⎯ Chip select signals (CS0 to CS3) output for each area
• Wait cycles can be inserted using an external WAIT signal
• External access in minimum of two cycles
• Provision for idle cycle insertion to prevent bus collisions
Direct memory access
controller (DMAC)
(4 channels)
• DMA transfer possible for the following devices:
⎯ External memory, on-chip memory, on-chip peripheral modules (excluding DMAC, UBC,
BSC)
• DMA transfer requests by on-chip modules
⎯ SCI, A/D converter, ATU-II, HCAN-II, SSU*
• Cycle steal or burst mode transfer
• Dual address mode
⎯ Direct transfer mode
⎯ Indirect transfer mode (channel 3 only)
• Address reload function (channel 2 only)
• Transfer data width: Byte/word/longword
Note: * SSU: Synchronous Serial Communication Unit
