GENERAL DESCRIPTION
   The ADMCF328 is a low cost, single-chip DSP-based controller, suitable for permanent magnet synchronous motors, and brushless dc motors. The ADMCF328 integrates a 20 MIPS, fixed-point DSP core with a complete set of motor control and system peripherals that permits fast, efficient development of motor controllers.

   The DSP core of the ADMCF328 is the ADSP-2171, which is completely code-compatible with the ADSP-21xx DSP family and combines three computational units, data address generators and a program sequencer. The computational units comprise an ALU, a multiplier/accumulator (MAC) and a barrel shifter. The ADSP-2171 adds new instructions for bit manipulation, multiplication (× squared), biased rounding and global interrupt masking.
