You have to reconfigure network settings on the PC or on the ZGP323
ICE before using the emulator.
Connecting Target Pod
Use an appropriate target pod and pin converter to connect the ZGP323
ICE to the target board. Figure 1 on page 4 illustrates the ZGP323 ICE top
panel connectors and Figure 2 on page 4 illustrates the ZGP323 evaluation board included with the kit. The 20- and 28-PDIP target pods plug
into the associated PDIP sockets on the target board. For example, if your
target board has a 20-SOIC socket, mate the 20-PDIP target Pod onto the
20-PDIP to 20-SOIC converter. Then install the target pod and converter
assembly into the board’s 20-SOIC socket

Connecting ZGP323 ICE to the Target Pod
After installing the appropriate target pod (and converter, if required) onto
the target development board, connect the ZGP323 ICE to the target pod
as follows:
•
For 40-PDIP and 48-SSOP target pods:
– Connect the 20-circuit cable from P9 on the emulator to P2 on
the 40-PDIP target pod. (The 20-circuit cable is included in the
40/48-pin accessory kit, ZLP323ICE01ZAC, ordered separately).
User Manual

Note:
ZLP323ICE01ZAC has been replaced by an improved version,
ZCRMZNICE02ZACG.
– Connect the 34-circuit cable from P10 on the emulator to P1 on
the 40-PDIP target pod.
•
For 20-PDIP and 28-PDIP target pods:
– Connect the 34-circuit cable from P10 on the emulator to P16 on
the target pod. (Emulator connector P9 is not used).
Connecting ZGP323 ICE to OTP Programming Module (Optional)
After developing and debugging your software, follow the steps below to
connect the ZGP323 ICE to the OTP programming module so that you
can burn your code onto the OTP chip:
1. Connect the 40-circuit ribbon cable from the ZGP323 ICE OTP Programming connector to connector P1 on the OTP programming module.
2. The 40-PDIP ZIF socket on the OTP programming module is
designed to accept 40-PDIP OTP chips. The OTP programming
adapters supplied with the ZGP323 ICE allow you to adapt the ZIF
UM019606-0408 Introduction

Z8 GP™ ZGP323 In-Circuit Emulator
socket to accept 20/28-PDIP chip packages.Other adapters are available separately, see Z8 GP Package Support and Ordering Informa-
tion on page 34 for more information.
After installing the OTP chip into the ZIF socket (or programming
adapter), you can program the chip using the instructions provided in
OTP Programming on page 25.
Connecting ZGP323 ICE to a PC
You can connect the ZGP323 ICE to a host PC using either an Ethernet or
USB port. To connect the ZGP323 ICE to a host PC using Ethernet, see

Setting Up Ethernet Communications
The default IP address and subnet mask of the ZGP323 ICE are
192.168.1.50 and 255.255.255.0, respectively. To enable communication
between the PC running ZDS II and the ZGP323 ICE, you must either
change the PC’s Ethernet settings to match those of the ZGP323 ICE or
vice versa.
If using the PC in a stand-alone configuration, set the PC’s IP address to
192.168.1.21 and its subnet mask to 255.255.255.0. For more details, see
Changing the PC’s Settings to Match the ZGP323 ICE.
In a networked environment, set the ZGP323 ICE IP address and subnet
mask to match the network setup. For more details, see Changing
ZGP323 ICE Settings on page 13.

Sample Project
After installing the ZDS II software and setting up the hardware, you are
ready to execute the sample software project to verify proper emulator
operation and to test with the Trace and Event system. This section
describes how to run the emulator in the in-circuit mode.
Z8 GP™ ZGP323 In-Circuit Emulator
User Manual

Notes:
Note:
1. If you run the emulator with a target attached, the emulator’s voltage
comparator is designed to serve as a target power sensor, and not as
a precision voltage measurement device. If you set the Target VCC to
match your target and the target’s voltage drifts downward, the power
sensor may no longer detect it. The emulator may therefore not connect to the target. In such cases, set the Target VCC voltage progressively lower until a proper connection is established.
2. If the ZGP323 evaluation board supplied with the kit is used, refer to

Collecting a Trace
Follow the steps below to obtain a sample trace:
1. Collect a simple trace by starting the program, stopping it, and viewing the trace buffer. Click Go button in the toolbar, wait a
moment, and then click Break button. The Trace buffer acts as a
ring buffer that continuously fills and then overwrites itself until you
stop execution.

Collecting Trace After an Event
The Trace and Event System is also used to capture trace data after an
event. Set up the events as described in Using an Event to Stop Execution
on page 22. In the Then: section, check Event Position in Buffer radio
button instead of Break. Use the slider bar to select the number of cycles
from the 64K buffer to be captured after the event.
When the event is detected, the selected number of cycles after the event
are collected. Execution stops after the cycles are collected. After the
event, selected number of cycles are left in the trace buffer.
Single-Stepping Through a Program
ZDS II provides a simple mechanism for single-stepping through a program. Follow the steps below to single-step through a program:

OTP Programming
Use the ZGP323 ICE OTP Programming Module to burn your program
onto a Z8 GP family chip. There are two ways to burn an OTP chip:
1. Burn Code from the Current Project
2. Burn Code from an Existing Hex File
Note:
Do not connect to the emulator when programming windowed CDIP
parts, see Burn Code from an Existing Hex File on page 29 when CDIP
programming windowed CDIP parts.

LED Indicators
There are three sets of dual LED indicators on the ZGP323 ICE, as
described below:
1. The dual ICE RUN LED on the front panel, see Figure 5 on page 8,
indicates emulator status. If the top LED is ON, the emulator is executing your system code. When the top LED is off, emulation has
stopped. If the bottom LED is ON, the emulator is not functioning
properly, contact technical support for assistance.
2. The dual 3.3 V DC/1.8 V DC LED on the rear panel, see Figure 4 on
page 7, indicates the status of internal voltages. Both LEDs are
normally illuminated when power is connected.
3. The dual LAN/LINK LED on the rear panel, see Figure 4 on page 7,
indicates Ethernet status. The LINK LED indicates that the Ethernet
connection is live. The LAN LED indicates that data is being transferred across the connected network.

External Interface Connectors
There are five external interface connectors (P8, P9, P10, J4, and J5) on
the ZGP323 ICE as explained below:
•
Connectors P9 and P10 are used to connect the emulator to the target pod and adapter board assembly, see Figure 1 on page 4.
•
The OTP Programming connector P8 is used to connect the emulator to the OTP programming module.
•
Connector J4 on the emulator front panel, see Figure 1 on page 4
and Figure 5 on page 8, provides a ground connection on all three
pins.
•
Connector J5 on the emulator front panel, see Figure 1 on page 4,
provides access to the following functions:
UM019606-0408 Sample Project
Page 36
Z8 GP™ ZGP323 In-Circuit Emulator
– Pin 3 provides a HIGH external trigger out for use in triggering
a device such as a logic analyzer or oscilloscope. Pin 3 is under
software control, and can be activated through the ZDS II Trace
and Event system. The trigger can be set to toggle or pulse.
– Pin 1 provides an input for an external HIGH or LOW trigger in,
allowing use of an external trigger as an event for the ZDS II
Trace and Event system.
Using J5 Pin 3, External Trigger Out
The ZGP323 ICE external trigger out feature is always enabled. Set the
Trace and Event system parameters, before executing the code. When the
set up event occurs, pin 3 of connector J5 goes HIGH and stays HIGH as
long as the event is active. Longer the event window, longer the trigger
out stays HIGH.
User Manual
33
Using J5 Pin 1, External Trigger In
The ZGP323 ICE external trigger in feature can be enabled as follows:
•
With the ledblink_c.zdsproj project open in ZDS II as
described in Sample Project on page 18, select To ol s ––> Trace
and Event System.
•
In the Trace and Event System window, select an Event entry. In
the When section, check Trigger In checkbox.
•
Select either 0 or 1 to trigger on LOW or HIGH, respectively
(edge-triggering not supported).
•
Click OK to set the Trace and Event System parameters. If you set
trigger=1 in the Trace and Event System window, then a HIGH on
pin 1 of connector J5 generates an event in the ZDS II Trace and
Event System. If you set trigger=0, then a LOW on pin 1 of connector J5 generates an event.
