DESCRIPTION
The μPD72001 advanced multiprotocol serial controller (AMPSC) is a high-performance, single-chip, serial communications controller designed to meet a wide variety of communications requirements. The AMPSC contains two independent full-duplex channels, which can be configured to transmit and receive data in either asynchronous protocol or one of two synchronous protocols: character-oriented protocol (COP) or bit-oriented protocol (BOP). The COP and BOP synchronous protocols include cyclic redundancy check (CRC) generation and checking.
