Overview
1-8
• Interrupt Controllers (x2)
• DMA Controller
• External Bus Interface
• Chip Integration Module (CIM)
— Separate clock output pins
— Support for up to 110 interrupt sources per interrupt controller organized as follows:
— Seven external interrupt signals
— Unique vector number for each interrupt source
— Ability to mask any individual interrupt source or all interrupt sources (global mask-all)
— Support for hardware and software interrupt acknowledge (IACK) cycles
— Combinatorial path to provide wake-up from low power modes
— Four fully programmable channels
— Dual-address transfer support with 8-, 16- and 32-bit data capability along with support
— Source/destination address pointers that can increment or remain constant
— 24-bit byte transfer counter per channel
— Auto-alignment transfers supported for efficient block movement
— Bursting and cycle steal support
— Software-programmable connections between the four DMA channels and the 14 DMA
— Glueless connections to external memory devices (e.g., SRAM, Flash, ROM, etc.)
— SDRAM controller supports 8-, 16-, and 32-bit wide memory devices
— Support for n-1-1-1 burst fetches from page mode Flash
— Glueless interface to SRAM devices with or without byte strobe inputs
— Programmable wait state generator
— 32-bit bidirectional data bus
— 24-bit address bus
— Up to eight chip selects available
— Byte/write enables (byte strobes)
— Ability to boot from external memories that are 8,16, or 32 bits wide
— System configuration during reset
— Selects one of four clock modes
– 103 fully-programmable interrupt sources
– 7 fixed-level interrupt sources
for 16-byte (4 x 32-bit) burst transfers
requesters in the UARTs (6), 32-bit timers (4), and external logic (4)
