4.1 INTRODUCTION
The ISCC™ provides two independent full-duplex chan-
nels programmable for use in any common asynchronous
or synchronous data communication protocols. The data
communication protocols handled by the SCC cell within
the ISCC are:
Asynchronous Mode
Character-Oriented Mode
Monosynchronous
Bisynchronous
External Synchronous
Bit-Oriented Mode
SDLC
SDLC Loop Mode
U
C
D
4.1.1 General Description of the Transmitter
A block diagram of the transmitter is given in Figure 4-1.
The transmitter has an 8-bit Transmit Data register (WR8)
loaded from the internal data bus and a Transmit Shift
register loaded from either WR6, WR7, or the Transmit
Data register. In byte-oriented modes, WR6 and WR7 can
be programmed with sync characters. In Monosync mode,
an 8-bit or 6-bit sync character is used (WR6), whereas a
16-bit sync character is used (WR6 and WR7) in Bisync
mode. In bit-oriented synchronous modes, the flag
contained in WR7 is loaded into the Transmit Shift register
at the beginning and end of a message.
