MC68302 Applications
protocol, where a 16x oversampling is employed to effectively extract the clock information
from the data. With transparent mode (and all the other protocols), this clock can be gener-
ated internally with a baud rate generator or can be provided externally.
D.8.2 Applications for Transparent Mode
There are several basic applications for the use of transparent mode.
First, some data may need to be moved serially but may not require protocol superimposed
— for example, voice data. There is no reason to encode voice data, and no error correction
is needed. With voice data, an occasional dropped bit will not interfere with the data stream
in any significant way. The MC68302 transparent mode works well for this type of applica-
tion.
Second, some board-level applications require a serial-to-parallel and parallel-to-serial con-
version. Often this is done to allow communication between chips on the same board. The
