MCF5213 Family Configurations
8
Interrupt controller
— Uniquely programmable vectors for all interrupt sources
— Fully programmable level and priority for all peripheral interrupt sources
— Seven external interrupt signals with fixed level and priority
— 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
DMA controller
— Four fully programmable channels
— Dual-address transfer support with 8-, 16-, and 32-bit data capability, along with support for
— 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 DMA requesters for the UARTs (3) and 32-bit timers (4)
Reset
— Separate reset in and reset out signals
— Seven sources of reset:
— Status flag indication of source of last reset
Chip integration module (CIM)
— System configuration during reset
— Selects one of six clock modes
— Configures output pad drive strength
— Unique part identification number and part revision number
16-byte (4 x 32-bit) burst transfers
– Power-on reset (POR)
– External
– Software
– Watchdog
– Loss of clock
– Loss of lock
– Low-voltage detection (LVD)
