ZiLOG Debug Interface
PS013014-0107
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 through a two-wire inter-
face that is connected to the ZPAK II emulator.
target board, ZPAK II, and the host PC running ZDS II. For more information on ZPAK II
and ZDS II, refer to www.zilog.com.
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 eZ80L92 system clock frequency.
