     29Freescale Semiconductor’s PowerQUICC™ MPC860 family is designed to deliver a versatile, on-chip integrated processor and
     30peripheral combination that can be used in a variety of controller applications—excelling particularly in communications and networking products. Providing functionality beyond the MPC850 family, the MPC860 family and MPC855T derivative are engineered to provide higher performance in all areas of device operation including flexibility, extensions in capability and integration.
     31= Overview =
     33The MPC860 architecture integrates two processing blocks: the embedded 8xx core compatible with the Power Architecture™ technology instruction-set architecture (ISA), and the communications processor module (CPM). The CPM is a dedicated RISC-based communications engine designed to support four serial communications controllers (SCCs), providing a total of eight serial channels: four SCCs, two serial management controllers (SMCs), one serial peripheral interface (SPI) and one I<sup>2</sup>C interface. This dual-processor architecture is designed to provide superior performance over traditional architectures because the CPM offloads communications intensive processing from the embedded 8xx core. This partitioning frees up the 8xx core to perform other system functions.
