It supports bit-oriented and character-oriented (byte count and byte control) synchronous data link controls as well as asynchronous protocols. The SC26C562 interfaces to synchronous bus MPUs and is capable of program-polled, interrupt driven, block-move or DMA data transfers. The SC26C562 (CDUSCC) is (PIN) hardware and (REGISTER) software compatible with the existing SCN26562 (DUSCC). CDUSCC will automatically configure to the NMOS DUSCC register map (default mode) on power up. The operating mode and data format of each channel can be programmed independently. Each channel consists of a receiver, a transmitter, a 16-bit multifunction counter/timer, a digital phase-locked loop (DPLL), a parity/CRC generator and checker, and associated control circuits. The two channels share a common bit rate generator (BRG), operating directly from a crystal or an external clock, which provides sixteen common bit rates...
