6.3 SCC 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 modes. 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.
