e-ICE Operating Notes
HT-IDE3000 Version
 Make sure the IDE3000 in use is the latest version before using the e-ICE.
Check the e-ICE version from “Help\About HT-IDE3000…” in the IDE3000 function list.
 If the version is V7.4 or above, when the IDE3000 is activated, the IDE will auto-detect
the version info and suggest if it is necessary to upgrade, or click “Help\Check Live
Update…” for a manual upgrade.

System Frequency
 For simulation convenience, check the red box as shown in the figure below to select
an MEV board supplied DEV operating frequency source. During e-ICE simulation an
externally connected HXT, ERC or LXT oscillator is not permitted. However, the
required oscillator should be connected for actual IC applications.

If the red frame is unchecked, the DEV operating frequency will not be supplied by the
MEV Board.
If the red frame is checked, the MEV Board provides frequencies as listed in the following table.
The MEV Board provided frequencies are integer divisions of 24MHz : 24 / N (N=2, 3, 4 … 60) and

Table 1 MEV Board provided frequencies
 The MEV Board can offer frequency division ratios as listed in Table 1. For other
frequency selections an external oscillator is required.
 The e-ICE can support a max system frequency of 20MHz. However as the MEV Board
is unable to divide a 20MHz frequency, external components will be required.
Voltage and Current
 The e-ICE operating voltage can be set freely to a range of 2.2V~5.5V which is
different from the HT-ICE which can only operate at either 5V or 3.3V.
 As the figure below shows, ensure that the emulator operates at the correnct voltage
using the SysVolt setting.
Figure 15 SysVolt Frequency Setup Window
 When the e-ICE uses an external VDD as the power supply, ensure that the external
power is stable and is not greater than 5.5V before connecting it to the VEXT and VSS
pins of the DEV Board. The J8 jumper should be connected between pins 2-3. When
switching the external power supply on or off, it is possible that instantaneous large
voltages or currents may be generated. Therefore remember to remove the external
power from the DEV Board before shutting down the power.
 When jumper J8 is connected between pins 1-2, then power will be supplied by the
internal VDD. Here the maximum current consumption is 300mA. If the power
consumption exceeds this value, then jumper J8 must be connected between pins 2-3
and power supplied on VEXT using an external power supply.

Note2: In this condition, it is not necessary for the Reset pin to be connected to an
external Reset circuit. To implement a reset select the IDE3000
icon.
Note3: In this condition, the Reset pin must be connected to an external Reset circuit or
the IDE3000 will show the following message during compilation:
Error (D1014): Unable to write resource option

e-ICE User’s Guide
ADC Sampling
In order to increase ADC sampling stability, it is recommended to add a 0.1F
non-polarized capacitor between each ADC channel and GND. The capacitor should be
located as closed to the DEV as possible.
If this capacitor is not connected, there may be 0~5 data value errors between the
sampled and the expected value which accounts for about 0~7mV.
Additionally, it is recommended to use an external power supply for VDD instead of using
the internal power. To do this, set jumper J8 to position 2-3 and connect an accurate
external power supply which will help to increase the ADC sample accuracy.
WDT Overflow Reset
If the WDT, in the normal mode, is required to overflow repeatedly, it may stop
overflowing after a period of time and the following condition may occur:
 Reset and power on reset may fail.
 Unable to STOP
These are ICE restrictions. To rectify, re-plug the USB interface and re-compile the
program to continue operation.
PRM Register
For those MCUs with the PRM registers, the MCUs with the pin switch function can be
applied with more flexibility. If no pin function should be changed, the PRM register
setting can be ignored and it default value is 00H. If the pin function is to be changed,
enable the pin switch function and give values according to actual needs. For details refer
to the datasheet on Holtek’s official website.
e-ICE HIRC Trim Operating Description
After Manufacture with no Prior Frequency Calibration then Manual
Adjustment will be Required
In this situation, after connecting to the e-ICE, the final configuration option selection is
“ICE_HIRC_Trim”. The IDE3000 provides a trimming interface for users to execute an
HIRC Trim function.
Note：
1. Each time a Project Rebuild is executed, a HIRC Trim should be re-executed.
2. Each time the HIRC frequency is changed, a HIRC Trim should be re-executed.
3. Each time the DEV Board is changed, a HIRC Trim should be re-executed.
4. After the Trim process has completed, if the HIRC frequency and DEV Board are not
changed, then the relevant information regarding the Trim will be stored automatically
without needing to re-trim again.

e-ICE User’s Guide
HIRC Trim Operating Procedures:
 Connect the e-ICE to a PC, execute IDE3000.exe and start a new operation with Trim
HIRC.
 The Configuration Options include setting the operating voltage and the HIRC as the
system frequency using the following steps:
 Set the operating voltage SysVolt according to actual requirements.
 Configure the SysFreq to have the system frequency provided by the internal DEV
or by an external oscillator supplied by the user
 Set VDD (for Internal RC selections) according to actual requirements
 Set the Internal RC according to actual requirements
 Configure OSC to have a system frequency to be provided by the internal DEV HIRC
13
e-ICE User’s Guide
 Click the “ICE_HIRC Trim” from the Option menu, then scroll and use an oscilloscope
to check that Fsys is the desired HIRC frequency.
 The Flat Tuning is the HIRC coarse adjustment while the Fine tuning is the HIRC
fine adjustment as shown as figure 17.
 As scrolling approaches the Max value the frequency will increase
 The present HIRC frequency can be measured on the Fsys pin on the DEV (A13 of
J1) as shown in figure 18.
 The oscilloscope detection method is shown in figure 19.

In this situation, after connecting to the e-ICE, the final configuration option selection is
not “ICE_HIRC_Trim.”
If it is necessary to check the present HIRC frequency accuracy, then set the options to
HIRC and measure according to figure 18 and 19 after downloading the compiled data.
M1001A Limited Version Operating Limitations
The following operating limitations only occur on the M1001A. The present MEV Board
has corrected these issues.
Stack Overflow
When an interrupt occurs, two false levels will be added to the stack which will create an
erroneous stack display. However it will not affect the program execution. To resolve this
issue, turn off the Detect Stack Overflow in the IDE3000 to close the message box.

Halt Instruction
 The Halt instruction cannot be located at the last address (0x1fff) of Program Memory
ROM Bank0.
 If a WDT overflow occurs during a Halt condition, it is possible that an erroneous stack
overflow may occur.
 Pressing Stop during a Halt condition may result in incorrect PC values.
 The first instruction after waking up from a Halt condition may execute correctly. To
resolve this issue add a NOP instruction to avoid this problem.
 Executing a HALT instruction using Single Step may cause an immediate wake up.
Configuration Option IO/RES Setting
When the “PXn/RES Pin Option in the Configuration Options is set as an I/O PIN, the I/O
Reset, Poweron Reset, and Stop will all be invalid.
