10.3.5
System Interrupt
The System Interrupt is the wired-OR of the interrupt signals coming from:
the Memory Controller
the Debug Unit
the System Timer
the Real-Time Clock
the Power Management Controller
The clock of these peripherals cannot be controlled and the Peripheral ID 1 can only be used
within the Advanced Interrupt Controller.
10.3.6
External Interrupts
All external interrupt signals, i.e., the Fast Interrupt signal FIQ or the Interrupt signals IRQ0 to
IRQ6, use a dedicated Peripheral ID. However, there is no clock control associated with these
peripheral IDs.
10.4
External Bus Interface
Integrates three External Memory Controllers:
– Static Memory Controller
– SDRAM Controller
– Burst Flash Controller
Additional logic for NAND Flash/SmartMedia and CompactFlash support
Optimized External Bus:
– 16- or 32-bit Data Bus
– Up to 26-bit Address Bus, up to 64-Mbytes addressable
– Up to 8 Chip Selects, each reserved to one of the eight Memory Areas
– Optimized pin multiplexing to reduce latencies on External Memories
Configurable Chip Select Assignment:
– Burst Flash Controller or Static Memory Controller on NCS0
– SDRAM Controller or Static Memory Controller on NCS1
– Static Memory Controller on NCS3, Optional NAND Flash/SmartMedia Support
– Static Memory Controller on NCS4 - NCS6, Optional CompactFlash Support
– Static Memory Controller on NCS7
10.5
Static Memory Controller
External memory mapping, 512-Mbyte address space
Up to 8 Chip Select Lines
8- or 16-bit Data Bus
Remap of Boot Memory
Multiple Access Modes supported
– Byte Write or Byte Select Lines
– Two different Read Protocols for each Memory Bank
Multiple device adaptability
