MCF5213 Family Configurations

— Programmable center or left aligned outputs on individual channels

— Four clock sources (A, B, SA, and SB) provide for a wide range of frequencies

— Emergency shutdown

• Two periodic interrupt timers (PITs)

— 16-bit counter

— Selectable as free running or count down

• Software watchdog timer

— 32-bit counter

— Low-power mode support

• Clock generation features

— One to 48 MHz crystal, 8 MHz on-chip relaxation oscillator, or external oscillator reference options

— Trimmed relaxation oscillator

— Two to 10 MHz reference frequency for normal PLL mode with a pre-divider programmable from 1 to 8

— System can be clocked from PLL or directly from crystal oscillator or relaxation oscillator

— Low power modes supported

— 2n (n ≤ 0 ≤ 15) low-power divider for extremely low frequency operation

• 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 16-byte (4×32-bit)

burst transfers

— 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:

– Power-on reset (POR)

– External

– Software

– Watchdog

– Loss of clock

– Loss of lock

– Low-voltage detection (LVD)

— Status flag indication of source of last reset

• Chip integration module (CIM)
