- products equipped with the built-in RC oscillation circuit and clock backup function operate without a crystal oscillator connected. However, products not equipped with the built-in RC oscillation circuit and clock backup function do not operate. Because specification is different for each product, check the features of clock generation circuit in User's manual of each product.

ML610400 series/ML610300 series How should I terminate the VDDX, XT0, and XT1 pins when the 32.768 kHz crystal is not connected?
This LSI does not correctly operate if the 32.768 kHz low-speed clock is not supplied. Please be sure to connect the 32.768 kHz crystal oscillator. Related Products: ML610(Q)40x, ML610(Q)42x, ML610(Q)47x, ML610(Q)48x, ML610Q30x, ML610Q35x, ML610Q36x, ML610Q38x, ML610Q41x, ML610Q43x, ML610Q46x, ML620Q416/ML620Q418
ML7344JC/ML7406C cannot be operated using the crystal.
Since TCXO is the initial setting in ML7344JC and ML7406C, 0x93 should be written first in [CLK_SET2:B0 0x03] register when the crystal is used. Related Products: ML7344/ML7406 family
Is a 32.768 kHz crystal external to the module required?
No. It is not required. Since MK71511/MK71521 feature a built-in 32.768 kHz crystal oscillator, no external crystal is required. Although MK71511A/MK71521A do not contain the 32.768 kHz crystal oscillator, the RC oscillator of the on-board SoC (nRF52811/nRF52832) and the like can be used. Note that the frequency deviation when using the built-in RC oscillator is ± 2%, and periodic calibration is required to ensure the frequency deviation of ± 250 ppm. Products: Bluetooth® low energy Modules
ML7396B cannot be operated using TCXO.
Since the crystal is the initial setting in ML7396x, 0xDF should be written first in [CLK_SET:B0 0x02] register when TCXO is used. Related Products: ML7396 family
How should I select between crystal oscillator/ceramic oscillator and built-in RC oscillator in ML22Q53x, ML22Q62x, and ML22Q66x?
Switching between crystal oscillator/ceramic oscillator and built-in RC oscillator is set in the Speech LSI Utility used when creating voice code data. Please see "4.2.1.2.10. User setting Parameter Dialog (ML22(Q)53x/62x/66x)" in the Speech LSI Utility User's Manual. Please select “Source clock oscillation” here. Please select “X'tal” when using an external clock.

请问CS+ For CA中的Set user option byte 有什么用？改成NO之后，为什么代码不能正常执行？
在CS+ for CA中，"Set User Option Byte" 是一个功能，用于设置微控制器的用户选项字节（User Option Byte）。用户选项字节是一组特殊的位，用于配置和控制微控制器的某些功能。通过更改选项字节中的特定位，可以实现不同的功能配置。将 "Set User Option Byte" 设置为 "NO" 可能导致代码不能正常执行的原因是，这取决于具体的用户选项字节配置和所使用的微控制器型号。通常情况下，用户选项字节的位表示不同的功能或工作模式，而设置为 "NO" 可能会禁用某些功能或模式，从而导致代码在期望进行某些操作时出现问题。举例来说，如果选项字节中的某个位用于启用外部晶体振荡器（External Crystal Oscillator）作为时钟源，而你将其设置为 "NO"，那么微控制器可能会切换到其他时钟源，例如内部RC振荡器（Internal RC Oscillator），这可能导致时钟频率不准确，进而影响代码的正确执行。因此，在修改用户选项字节之前，建议仔细阅读相关的微控制器文档、编程手册或应用笔记，了解每个选项位的含义和影响，以确保正确地配置选项字节，以及理解设置 "NO" 可能会导致的影响。
For Analog Audio Processors, How should unused input signal pins be handled in a product that operates with One or Two Positive Power Supplies?
Since the voltage at the input terminal is a Bias Voltage, it is recommended to connect it to GND via a Coupling Capacitor. It is also possible to leave OPEN the unused input signal pins, but External Noise, Crosstalk, etc. are more likely to occur.
ROHM’s Product Longevity Program Enables Worry-free Adoption of ROHM Products
ROHM is working on a Product Longevity Program to eliminate these customer concerns, burdens, and risks as much as possible, allowing customers to select products with confidence.
ML610400 series/ML610300 series The item "Note" of "Clock Generation Circuit"of User's Manual describes that operation is not guaranteed if the low-speed clock is not supplied to this LSI. However, is it possible to operate the LSI with the 500 kHz RC oscillation alone when only the peripheral circuits that do not use 32.768 kHz are used?
Please be sure to supply the low-speed clock. If the 32.768 kHz low-speed clock is not supplied to this LSI, the low-speed oscillation stop detecting function to monitor the low-speed clock is activated to generate a reset.

请问CS+ For CA中RL78/G13的Set user option byte设置成NO，默认存储的是0还是1(资料上没找到)，还有就是LVD设置有什么用？且想问下设置成NO和yes有什么差别？
将 “Set User Option Byte“ 设置为 “NO“ 可能会导致代码不正常执行。通常情况下，用户选项字节的位表示不同的功能或工作模式，如启用外部晶体振荡器（External Crystal Oscillator）作为时钟源，而设置为“NO“，那么微控制器可能会切换到其他时钟源，例如内部RC振荡器（Internal RC Oscillator），这可能导致时钟频率不准确，进而影响代码的正确执行。 LVD低电压检测电路，是监视MCU工作电压的电路。他和选项字节相关联，把工作电压和一个用户设定的检测电压相比较，然后根据比较的结果，决定是产生一个内部复位信号，还是产生一个内部中断信号。
