3.3SCC Data Encoding Methods

The SCC provides four different data encoding methods, selected by bits D6 and D5 in WR10. These four include NRZ, NRZI, FM1 and FM0. The SCC also features a digital phase-locked loop (DPLL) that can be programmed to operate in NRZI or FM mode. Also, the SCC contains two features for diagnostic purposes, controlled by bits in WR14. They are local loopback and auto echo.

For further information on these subjects or any others involving the SCC, contact the manufacturer of the SCC being used for a complete technical manual.
