Caution:
The serial data on the DBG pin is sent using the standard asynchronous data format
defined in RS-232. This pin can interface the Z8 Encore! XP
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
page 196.
