If CTS is already asserted when RTS is asserted, transmission begins in two additional bit
times. If CTS is not already asserted when RTS is asserted and CTSS = 0, then transmis-
sion begins in three additional bit times. If CTS is not already asserted when RTS is asserted
and CTSS = 1, then transmission begins in two additional bit times.
7.10.12 Digital Phase-Locked Loop (DPLL)
DPLL data encoding and DPLL operations are discussed in the following paragraphs.
7.10.12.1 DATA ENCODING. Each SCC contains a DPLL unit that may be programmed to
encode and decode the SCC data as NRZ, NRZI Mark, NRZI Space, FM0, FM1, Manches-
ter, and Differential Manchester. Examples of the different encoding methods are shown in
Figure 7-43.
If it is not desired to use the DPLL, the NRZ coding may be chosen by the user in the GSMR.
The definition of the encodings are as follows:
