OCD Interface
Figure 23. Interfacing the On-Chip Debugger’s DBG Pin with an RS-232 Interface (1)
The following sections describes the operation of OCD.
The OCD uses the DBG pin for communication with an external host. This one-pin
interface is a bidirectional open-drain interface that transmits and receives data. Data
transmission is half-duplex, in that transmit and receive cannot occur simultaneously. The
serial data on the DBG pin is sent using the standard asynchronous data format defined in
RS-232. This pin creates an interface from the Z8 Encore! XP F0823 Series products to
the serial port of a host PC using minimal external hardware.Two different methods for
connecting the DBG pin to an RS-232 interface are displayed in
The recommended method is the buffered implementation depicted in
DBG pin has a internal pull-up resistor which is sufficient for some applications (for more
details on the pull-up current, see
operation at higher data rates or in noisy systems, an external pull-up resistor is
recommended.
