2. Automatic control interface
Connect the burner automatic control interface with the automatic machine through wire, and the automatic
machine sends out the start signal to trigger the burning, and detect the OK, BUSY, FAIL status signal sent by
the burner to control the operation of the machine, and then carry out automatic batch burning. The
connection mode of the burner automatic control interface and the automatic machine is shown in the figure

3 Offline burning operation and description
3.1 Basic operation
The basic burning steps are as follows：
1. Connect the burner to the computer through the USB cable and load the user program data file *.hex in
WriterConfig, and then configure and download to the burner. (More information, see chapter 3.2
“WriterConfig” configuration download description.)
2. Insert the "burning connection flat cable" into the burning interface, connect the burner and the chip
module, and connect to power supply. Or connect the burner control interface to the automaton table in
mass production, and connect the power supply (See Chapter 2.4 "The burner control interface
description and connection mode" for details).
3. Recording by manually pressing the start button or the start signal from the automatic machine.
3.2 Use WriterConfig for program and configuration download
Figure 9. CMT216x Writer Config Master Interface
Steps for downloading the burning target Hex to offline burner:
1. Select the “OTP”, which means the operation burning target is the import Hex file in OTP.
2. Click “Add File…”, import the target burning Hex file；
3. Click “Setting…”, choose the required burning option；
4. Click“Download to Writer”, download the target Hex and burning options to the offline writer, after

3.2.1 Burning option description
Click “Setting…” the interface of burning option and the descriptions are shown as followed.
Figure 10. CMT216xA MCU Setting Interface（Burning option part）
Table 10. CMT216x MCU Setting Description
No. Option Description
1 Encrypt
Code The enabling user code encryption option. It is not recommended temporarily.
2 NoXoMode
Disable external crystal (26MHz) mode. This will save cost for situations of no require of
high frequency transmission.
It should be noted that CMT216x chip needs to be
connected to the external 26MHz crystal during the initial power-on self-test by default.
Otherwise, the user program will not operate if self-test fails.
3 User User mode option. If this option is selected, the chip will be burned to User mode. For
details of the User mode feature, see the AN290 CMT216xA User manual
4 Exe User
Boot
User code execution option. If this option is selected, the user code will be automatically
executed after being loaded. If unchecked, user code is only loaded into PRAM, but not
executed.
5 Run Run mode option If this option is selected, the chip will be burned into Run mode (that is, finished chip mode). For details about Run mode features, see the AN290CMT216xA
user manual
6 FTP Disable FTP protection switch option. If it is selected under the Run mode, the FTP protection
mechanism takes effect in Re-test mode and FTP access is prohibited. For details about
the protection mechanism and Re-test mode, see AN290 CMT216xA user manual.

No.
Option
Description
7 OTP
Disable
The OTP protection switch option. If the item is selected in Run mode, the protection
mechanism remains active in the Re-
test mode, and the OTP forbids access. For
protection mechanisms and Re-test mode features, see the
AN290 CMT216xA User
Manual.
8 S3S Disable
S3S Bus Switch Options. If the item is selected in Run mode, the S3S bus and 1-wire
debugging interface are disabled and the chip has been encrypted and cannot enter re-
test mode at the same time. If this parameter is not selected, S3S and 1-wire can be
opened in a special mode and enters Re-test mode. More details about Re-test mode,
see AN290 CMT216xA user manual
9 por_cal_dis
Disable the calibration option when the chip is powered on for the first time. After the
check, the chip will be banned for the first time on internal calibration processing, which
can shorten the time of the first power on to the user program execution (equivalent
power on reset time). Since the cancellation of calibration will affect the part function
modules, it is suggested to operate under the guidance of professionals.
10 Max Count It is used to limit the maximum times of burning in chip configuration.
3.2.2 User-defined serial number (SN) increment function and settings
Figure 11. CMT216xA MCU Setting Interface（SN setting part）
SN Settings Enable, select whether to synchronize the ID self-add function. When SN Settings in CMT216xA
MCU Setting is selected, related configuration items is shown in the following table.
Table 11. SN Settings in CMT216xA MCU Setting
No. Option Description
1 Start Addr (Hex) The start addresses of SyncID storing, with up to 8 bytes serial number
storing. The serial number is burned to specified address of OTP.

AN279
Rev 0.7 | 16/32
www.hoperf.com
No. Option Description
2 End Addr (Hex) The ending address of SyncID storing
3 Step Size After each chip is burned, the next ID will change incrementally according
to Step Size setting rule
4 Current SN(Hex)
1. SN changes according to the Current SN value when the chip is
continuously burned；
2. Both of the interface and Writer displayed ID value are hexadecimal
number；
3. SN最大支持范围为8字节。
5 Repeat Count The numbers of chips that are burned repeatedly until changing the ID.
6 Max Count Used to limit the maximum burning times of the chip
3.2.3 EEPROM initial burning value inside chip
Figure 12. CMT216xA MCU Setting Interface（Burn EEPROM part）
CMT216xA series chip has a 64-byte EEPROM internally, which can be saved by users as important
information on power failure. The default value of this part of memory is 0. When users burn the target
program, they can specify an initial value for the 64-byte EEPROM at the same time. Users just need to edit
the specify initial value into TXT text format as shown below. After that, select Burn EEPROM and loading the
file via Add File...

Note；
1. All the edit content is in hexadecimal (0-9, A-F, case unlimited)；
2. Use the byte unit, and insert spaces between each byte；
3. Users can define its content according to all 64 bytes or part of them, noted that the burner address is
written from 0x00, and the first 64 bytes are treated as valid content (ignored the exceed part and filled the
vacancy with 0, the chip default value).
4. EEPROM initial value burning function only supports edited content, and does not support self-increasing
burning of SN serial
