The I?C controller provides a 14-bit time-out counter to handle I2C bus hang-up. If the I2C bus is hung up, it causes I2CSTATUS and the flag SI not updated for a period, and the 14-bit time-out counter may overflow and acknowledge CPU the I2C interrupt. Refer to the following figure for the 14-bit t...

Before entering Power-down mode, the user can disable IRQ handling by calling the function __disable_irq (); which allows the system to continuously execute the next command when entering Power-down mode after wake-up without entering the interrupt process. In addition, the user also needs to consid...

The NuMicro? Cortex-M series chips support different USB controllers in different series, including USB 2.0 Full-speed device controller, USB 2.0 High-speed device controller, USB 1.1 Full-speed host controller, and USB On-The-Go (OTG) controller.
Detailed support list is as follows:

In general, it is suggested to use flux rather than solder paste when soldering components. After soldering is completed, alcohol or cleaning agent can be used to remove residual flux residues to avoid problems caused by a short circuit.

The Nu-Link driver may add the breakpoint information before full run of the program, and the breakpoints added during full run of the program will be added into the cache. Therefore, the newly added breakpoint can only be executed properly after the user stops and re-executes the program.

In USB host applications, Nuvoton MCUs will not take the initiative to provide 5V voltage to Vbus. Additional 5V needs to be designed for system circuit to provide to USB devices required to be connected. In NuTiny-SDK-M451 development board, for example, 5V is provided by the Nu-Link-Me ICE Debugge...

In the USB specification, the transmission rate of low-speed, full-speed and high-speed devices are 1.5 MB, 12 MB and 480 MB respectively. For the NuMicroTM series, some chips support full-speed device, full-speed host and high-speed device. In accordance with the signal sampling method, USB clock s...

A 9-bit data frame in the UART application includes 8-bit data and parity bit (9th bit), and is normally used in the RS485 application to indicate the address or data byte. Refer to (follow) the table below to control SPE bit, EPE bit, and PBE bit of UA_LCR register for parity bit (9th bit) level fi...
