HIRC, PLL, 时钟切换 Why can’t the clock source of HCLK be switched to PLL when the system clock source is initialized with the following commands? CLK->CLKSEL0 = (CLK->CLKSEL0 & ~CLK_CLKSEL0_HCLKSEL_Msk); CLK->CLKSEL0 |= CLK_CLKSEL0_HCLKSEL_PLL; 1480414232839 Q: Why can’t the clock source of HCLK be switched to PLL when the system clock source is initialized with the following commands? CLK->CLKSEL0 = (CLK->CLKSEL0 & ~CLK_CLKSEL0_HCLKSEL_Msk); CLK->CLKSEL0 |= CLK_CLKSEL0_HCLKSEL_PLL; A: In the execution of the first command line, CLK->CLKSEL0 = (CLK->CLKSEL0 & ~CLK_CLKSEL0_HCLKSEL_Msk); HCLKSEL (CLKSEL0 [2: 0]) is set to 0x00. When HCLKSEL is set to 0x00, as shown below, the clock source of HCLK is switched to external crystal. If the external crystal is not stable or enabled at this time, the switching clock source will fail and the HCLKSEL will be remain its default setting (initialized as 0x07, clock source as HIRC). Therefore, in the execution of the second command line, CLK->CLKSEL0

Offline Programming When using Nu-Link or Nu-Link Pro to do Offline Programming, what protection mechanisms are available for written files? 1482203753541 The options “Use Password for Offline Programming” and “Limit the Number of Offline Programming” are provided. Using Password can protect the file written to the offline Flash from being read. Limiting the number of offline programming can prevent private programming. Follow the steps below to enable the options: 1. After the ICP Programming Tool is opened, you can click on the "Options" in the "Programming" section, as shown in Figure 1, to enable programming options. Figure 1 2. In the "Programming" options, select the "Offline Programming Mode" in the "Operation" section, you can open the "Options for Offline Programming Mode" section, as shown in Figure 2. Figure 2 Check "Use Password for Offline Data" to enable data encryption. The user can enter a password of 1 to 32 characters in length, and have to enter the password once
FAQ / How to read the actual N76E003 band-gap voltage?
https://www.nuvoton.com.cn/support/technical-support/faq/d75a251a-04f1-11ea-b113-05daf7eedf03/
How to read the actual N76E003 band-gap voltage? 1482387076715 The N76E003 ADC can select an internal band-gap voltage as the input pin, which can be used to get the ADC reference voltage, for more accurate ADC results. At room temperature, all N76E003 band-gap voltage values will be calibrated within the range of 1.17V to 1.27V. If you want to get the actual band-gap value for N76E003, read the 2 bytes value after the UID address. There are 2 bytes after the UID address that store the actual band-gap value, but the actually valid bit is 12. The first byte is the upper 8 bits, and the lower 4 bits of the second byte are the lower 4 bits of the 12 bit. Reading and calculation steps: Read a bad-gap value with IAP by reading UID; Merge the upper 8 bits and the lower 4 bits; Use the following formula to convert to an actual voltage value. Formula: Calculation example: Read the 2 bytes value after the UID address, wherein the first bytevalue is 0x64, and the second bytevalue is 0x0E,
FAQ / Can FMC instructions be used to adjust the Data Flash size in the program?
https://www.nuvoton.com.cn/support/technical-support/faq/d79643de-04f1-11ea-b113-05daf7eedf03/
Can FMC instructions be used to adjust the Data Flash size in the program? 1493179003648 For the NuMicro® series that can set the Data Flash size, usercanmodify DFEN (Config0 [0]) to enable or disable Data Flash,and modify DFBADR (Config1) to set the base address of Data Flash and adjust the Data Flash size. After the setting, the program needs to write 1 to CHIPRST (SYS_IPRST0 [0]) for software chip reset. With software chip reset, the new setting will take effect. Sample code is as follows: uint32_t au32Config[2]; SYS_UnlockReg(); FMC_Open(); FMC_ReadConfig(au32Config, 2); FMC_ENABLE_CFG_UPDATE(); au32Config[0] &= ~0x1; au32Config[1] = u32DFBA; FMC_WriteConfig(au32Config, 2) SYS_ResetChip();

NUC505, MTP, Cipher, ICP tool, Off-line ICP, Nu-Link pro How to use the ICP tool to do encrypted programming for the NUC505? 1543307764380 When using the ICP tool, offline programming or online programming can be used for encrypted programming of NUC505. The user must first switch the NUC505 to ICP mode before the ICP tool is connected. The online programming procedure is as follows: After connecting the NUC505 with the ICP tool, first place the bin file to be burned in the code, as shown in Figure 1. Set the MTP KEY as shown in Figure 2. The user must define the MTP KEY as the password (red box 1 in the figure), and then set the offset (red box 3 in the figure). The ICP tool will read the offset of the bin file as the MTP Signature (red box 2 in the figure). Finally, the red box 4 in the figure can be set to lock the MTP, that is, the MTP KEY cannot be changed again. Check Code and MTP and click Start to program the code and MTP KEY into the NUC505.
