Zilog Debug Interface
ZDI Overview
PS006614-1208
The Zilog Debug Interface (ZDI) provides a built-in debugging interface to the eZ80
CPU. ZDI provides basic in-circuit emulation features such as:
•
•
•
•
•
•
•
•
•
The above features are built into the silicon. Control is provided via a two-wire interface
that is connected to the ZPAK II emulator.
get board, ZPAK II, and the host PC running Zilog Developer Studio. For more informa-
tion on ZPAK II and ZDS II, refer to www.zilog.com.
Developer
The ZDI block for the eZ80190 device provides increased functionality from previous ver-
sions. ZDI allows reading and writing of most of the internal registers without disturbing
the state of the machine. New features allow READs and writes to memory to occur as fast
