Machine learning, ML, Continual breakpoints How to solve the problem that the Keil project can only run in debug mode but can't be executed normally when developing machine learning programs in C++ with the Nuvoton evaluation board and Arm library? 1683014520000 When the Keil project can run in debug mode but will get stuck if it is not connected to ICE in free-run mode, and it is found that the program continues to be stuck at a breakpoint from the debug mode, it may be a semihosting error. If some error messages such as "stdout/stdin/stderr multiply defined..." appear when using the Arm library in the Nuvoton machine learning examples, it will cause semihosting errors by deleting the repeatedly defined items directly and lead to the continued breakpoint appearing in the Keil project. Note: In order to avoid the semihosting errors, apart from deleting duplicate definitions, users need to add the following code in retarget.c: extern void $Super$$_sys_open(void); FILEHANDLE
Häufig gestellte Fragen / What are ISP, ICP and IAP?

What are ISP, ICP and IAP? 1423469461294 ISP stands for "In System Programming". The target chip runs the boot/loader code of LDROM through the peripheral interface such as USB/UART/SPI/I²C/RS-485/CAN... to update the internal APROM, Data Flash and User Configuration Word. ICP stands for "In Circuit Programming". PC runs the software “NuMicro ICP Programming Tool” through the SWD (serial wire debug) port of Nu-Link circuit to update the internal APROM, LDROM, Data Flash and User Configuration Word of the target chip. IAP stands for In-application-programming and it is a function for user to switch the code executing between APROM and LDROM without reset. User can enable the IAP function by re-booting chip and setting the chip boot selection bits in CBS (CONFIG0[7:6]) as 2 or 0. When chip boots with the IAP function enabled, any other page within the executable range of code can be mirrored to the first page of executable code (0x0000_0000~0x0000_01FF) any time.
Häufig gestellte Fragen / Does the NuMicro™ Cortex-M0/M4 Series support the code protected for user's program code? How to unlock the LOCK bit on the User Configuration Word?

Code Protection Does the NuMicro™ Cortex-M0/M4 Series support the code protected for user's program code? How to unlock the LOCK bit on the User Configuration Word? 1423471326414 Yes, the LOCK bit is provided on the User Configuration Word to protect user's program code. When this LOCK bit is set, all of the data on the Flash memory will be read back as 0xFFFFFFFF. At this time, the "Whole Chip Erase" operation should only be performed for the target chip to unlock the LOCK bit.
Häufig gestellte Fragen / What is the page size of erase and data size to program for Flash memory?
https://www.nuvoton.com.cn/support/technical-support/faq/d3f2b73b-04f1-11ea-b113-05daf7eedf03/
What is the page size of erase and data size to program for Flash memory? 1423471655304 It is 512 bytes per page to erase for Cortex-M0 and 2k bytes for Cortex-M4. The data size for per data to program is 4 bytes (a word).
Häufig gestellte Fragen / What series in theNuMicro Coretex™ - M0 Family supports UID (Unique ID)? What to do if the user wants to use a unique ID to encrypt a chip?
https://www.nuvoton.com.cn/support/technical-support/faq/d3f74b1e-04f1-11ea-b113-05daf7eedf03/
What series in theNuMicro Coretex™ - M0 Family supports UID (Unique ID)? What to do if the user wants to use a unique ID to encrypt a chip? 1388505600000 Er kann die UID (eindeutige ID) zur Verschlüsselung aller Chips in der NuMicro-Familie mit Ausnahme der NUC100AN- und NUC100BN-Serie nutzen. Im Hinblick auf UIDs (Unique ID) integriert Nuvoton diese wie oben erwähnt in die Chips; die UIDs aller Chips unterscheiden sich voneinander. Der Anwender kann einige Bewertungsregeln im Firmware-Code bereitstellen und so verhindern, dass der Originalcode gestohlen und das Produkt reproduziert wird.
Häufig gestellte Fragen / What is the clock source of RTC (Real Time Clock) controller? Does RTC operate in Power- down mode?
https://www.nuvoton.com.cn/support/technical-support/faq/d40099f4-04f1-11ea-b113-05daf7eedf03/
What is the clock source of RTC (Real Time Clock) controller? Does RTC operate in Power- down mode? 1423560530254 The only clock source of RTC controller comes from the LXT. Since the LXT still works in Power-down mode, RTC can operate and wake up the whole chip from this mode.

https://www.nuvoton.com.cn/support/technical-support/faq/d4052dd7-04f1-11ea-b113-05daf7eedf03/
Wie viele Timer-Controller gibt es in der NuMicro™-Familie? 1388505600000 Es gibt bis zu 4 Sets an 32-Bit-Timer-Controllern in einem Chip der NuMicro™-Familie, dies hängt jedoch von der Teilenummer ab. Timer und PWM-Timer sind unabhängig von der Auswahl der Taktquelle. Daher können Nutzer auch den SysTick- und PWM-Timer (falls PWM-Timer aktiviert, aber der PWM-Ausgang deaktiviert ist) als Timer nutzen.
Häufig gestellte Fragen / What are the resolutions of Pre-scaler and Timer counter in the Timer controller?

What are the operating modes of Timer controller? 1423648320000 The Timer controller provides One-shot, Periodic, Toggle and Continuous (Auto-reloaded) Counting Operation modes. It also provides the event counting function to count the event from an external pin and the input capture function to capture or reset the timer counter value. (The NUC100/NUC120 medium density only supports One-shot and Periodic modes.)

https://www.nuvoton.com.cn/support/technical-support/faq/d41b7503-04f1-11ea-b113-05daf7eedf03/
What is the Periodic Operation mode for Timer controller? 1423561976223 In Periodic Operation mode, the Timer will reset the 24-bit Timer counter and restart to count from 0 when each time the value of 24-bit up-counting Timer counter matches the setting of TCMPR (Timer Compare Register). At this moment, the Timer interrupt event flag (TIF) will be set by hardware and the interrupt signal is generated.
