Freescale Semiconductor
8
— 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 x 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)
— System configuration during reset
— Selects one of three clock modes
— Configures output pad drive strength
— Unique part identification number and part revision number
General purpose I/O interface
— Up to 56 bits of general purpose I/O
— Bit manipulation supported via set/clear functions
— Programmable drive strengths
— Unused peripheral pins may be used as extra GPIO
JTAG support for system level board testing

V2 Core Overview
The version 2 ColdFire processor core is comprised of two separate pipelines decoupled by an instruction buffer. The two-stage
instruction fetch pipeline (IFP) is responsible for instruction-address generation and instruction fetch. The instruction buffer is
a first-in-first-out (FIFO) buffer that holds prefetched instructions awaiting execution in the operand execution pipeline (OEP).
The OEP includes two pipeline stages. The first stage decodes instructions and selects operands (DSOC); the second stage
(AGEX) performs instruction execution and calculates operand effective addresses, if needed.
The V2 core implements the ColdFire instruction set architecture revision A+ with added support for a separate user stack
pointer register and four new instructions to assist in bit processing. Additionally, the MCF52235 core includes the enhanced
multiply-accumulate (EMAC) unit for improved signal processing capabilities. The EMAC implements a three-stage arithmetic
