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 patible 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 mon bit rate generator (BRG), operating directly from a crystal or an external clock, which provides sixteen mon bit rates simultaneously. The operating rate for the receiver and transmitter of each channel can be independently selected from the BRG, the DPLL, the counter/timer, or from an external 1X or 16X clock, making the CDUSCC well-suited for dual-speed channel applications. Data rates up to 10Mbits per second are supported. The transmitter and receiver each contain a sixteen-deep FIFO with appended transmitter mand and receiver status bits and a shift register. This permits reading and writing of up to...
