The On-Chip Debugger consists of four primary functional blocks: Transmitter, Receiver,
Autobaud Generator, and Debug Controller. Figure 41 illustrates the architecture of the
On-Chip Debugger.
The On-Chip Debugger (OCD) uses the DBG pin for communication with an external
host. This one-pin interface is a bidirectional open-drain interface that transmits and
