Caution:
Figure 21. 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 bidirectional open-drain interface that transmits and receives data.
Data transmission is half-duplex, which means transmission and data retrieval 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 between the Z8

For operation of the On-Chip Debugger, all power pins (V
