Table 2. MCF51AC256 Series Functional Units
Functional Unit
Function
CF1 Core (V1 ColdFire core)
Executes programs and interrupt handlers
BDM (background debug module)
Provides single pin debugging interface (part of the V1 ColdFire core)
DBG (debug)
Provides debugging and emulation capabilities (part of the V1 ColdFire
core)
VBUS (debug visibility bus)
Allows for real-time program traces (part of the V1 ColdFire core)
SIM (system integration module)
Controls resets and chip level interfaces between modules
Flash (flash memory)
Provides storage for program code, constants and variables
RAM (random-access memory)
Provides storage for program variables
RGPIO (rapid general-purpose input/output)
Allows for I/O port access at CPU clock speeds
VREG (voltage regulator)
Controls power management across the device
COP (computer operating properly)
Monitors a countdown timer and generates a reset if the timer is not
regularly reset by the software
LVD (low-voltage detect)
Monitors internal and external supply voltage levels, and generates a reset
or interrupt when the voltages are too low
CF1_INTC (interrupt controller)
Controls and prioritizes all device interrupts
ADC (analog-to-digital converter)
Measures analog voltages at up to 12 bits of resolution
FTM1, FTM2 (flexible timer/pulse-width
modulators)
Provides a variety of timing-based features
TPM3 (timer/pulse-width modulator)
Provides a variety of timing-based features
CRC (cyclic redundancy check)
Accelerates computation of CRC values for ranges of memory
ACMP1, ACMP2 (analog comparators)
Compares two analog inputs
IIC (inter-integrated circuit)
Supports standard IIC communications protocol
KBI (keyboard interrupt)
Provides pin interrupt capabilities
MCG (multipurpose clock generator)
Provides clocking options for the device, including a phase-locked loop
(PLL) and frequency-locked loop (FLL) for multiplying slower reference
clock sources
OSC (crystal oscillator)
Allows a crystal or ceramic resonator to be used as the system clock source
or reference clock for the PLL or FLL
LPO (low-power oscillator)
Provides a second clock source for COP and RTI.
CAN (controller area network)
Supports standard CAN communications protocol
SCI1, SCI2 (serial communications interfaces)
Serial communications UARTs capable of supporting RS-232 and LIN
protocols
SPI1 (8-bit serial peripheral interfaces)
Provides 8-bit 4-pin synchronous serial interface
SPI2 (16-bit serial peripheral interfaces)
Provides 16-bit 4-pin synchronous serial interface with FIFO
