Caution:
Figure 23.Interfacing the On-Chip Debugger’s DBG Pin with an RS-232 Interface (1)
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.
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!
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 depicted in Figures 23
and 24 . The recommended method is the buffered implementation depicted in Figure 24 .
The DBG pin must always be connected to V
RS-232 TX

For operation of the On-Chip Debugger, all power pins (V
must be supplied with power, and all ground pins (V
properly grounded.
