ZiLOG Debug Interface
PS015308-0404
Introduction
The ZiLOG Debug Interface (ZDI) provides a built-in debugging interface to the eZ80
CPU. ZDI provides basic in-circuit emulation features including:
•
•
•
•
•
•
•
•
•
The above features are built into the silicon. Control is provided via a two-wire interface
that is connected to the ZPAK II Debug Interface Tool. Figure 36 illustrates a typical setup
using a a target board, ZPAK II, and the host PC running ZiLOG Developer Studio. Refer
to the
Figure 36.Typical ZDI Debug Setup
ZDI allows reading and writing of most internal registers without disturbing the state of
the machine. Reads and writes to memory may occur as fast as the ZDI can download and
upload data, with a maximum frequency of one-half the CPU system clock frequency.
