The On-Chip Debugger consists of four primary functional blocks: transmitter, receiver,
auto-baud generator, and debug controller.
On-Chip Debugger.
The On-Chip Debugger uses the DBG pin for communication with an external host. This
one-pin interface is a bi-directional open-drain interface that transmits and receives data.
Data transmission is half-duplex, in that transmit and receive cannot occur simultaneously.
