How to generate the period of Timer?
Timeout Period = (Period of Input Clock Source) * (8-bit Prescaler + 1) * (24-bit TCMPR), (TCMPR: Timer Compare Register).
Please refer to the following NUC100 series example to get the longest and shortest period of Timer.

How many PWM channels the NuMicro® Cortex-M0 Series can provide?
There are up to 24 PWM channels in one NuMicro® Cortex-M0 Series chip, but the number of PWM channels provided in a chip depends on the part number.

What is the PWM generator and its main function?
PWM is the abbreviation of pulse-width modulation, and it can generate and provide the square waveform output from a chip.
User can control the frequency and duty of output waveform.
In general, the PWM output is used to drive the motor or LED.

How many slaves can join the LIN bus?
The protocol of LIN bus includes 6 bits of identifier field to indicate the length of the following data and what message the slave responds to. In other words, there are 64 identifiers sorted in 4 groups of 16 messages. Slaves must be designed to respond to one or more messages; as a result, the ma...

What is the difference of UART coding between high speed and low speed?
The UART coding between high speed and low speed is almost the same. First, we must know the only difference of UART hardware between high speed and low speed is buffer length. The buffer length is 64 bytes for high speed, but 16 bytes for low speed. Also, user must select good threshold for receive...

How to use UART /CTS to wake up a chip?
Please set the WKCTSIEN (UART_INTEN[9]) and MODEMIEN (UART_INTEN[3]) after initiating UART and /CTS function.
When the /CTS input pin changes the state from high to low or from low to high, it will generate the modem interrupt to wake up a chip.

Can Nuvoton provide the VID (0x0416) for customers?
The VID (0x0416) is licensed from USB-IF by Winbond. Nuvoton, a spin-out of Winbond Electronics’ Logic business group does not suggest that customers use the VID (0x0416) to design USB applications. Please refer to the following USB-IF website to license a Vendor ID for USB production. http://www.us...
