How to use UART RX Time Out interrupt?

To use UART RX Time Out interrupt, take UART0 as an example. When UART0 is initialized, call UART_SetTimeoutCnt to set the RX Time Out time, as shown below:

The RX Time Out setting has a valid value 40~255. The detailed description is as follows:

Is the external crystal (HXT) voltage of the M480 series and M451 series limited by 0.3VDD and 0.7VDD, the same as the e

The external crystal (HXT) voltage of the M480 series and M451 series is different from the external clock source voltage. There are two specifications as described below: The following table shows the specifications of the HXT voltage, which is an internal digital signal, independent of 0.7VDD. M48...

What is PDMA Stride Mode? How to use it?

Stride mode is a special PDMA mode, which can move the data of a certain memory to another memory with a fixed interval and quantity. For example, there is a continuous memory block. The content data is picture color information and the order is fixed to red, green, blue. With Stride mode, individua...

What should user do if the WDT (Watchdog Timer) Reset of the NUC505 does not work properly?

When the WDT Reset occurs in the NUC505, the hardware mechanism of the WDT will pull the voltage of reset pin low to trigger reset; if the voltage of the Reset pin cannot be pulled low, the reset will not be triggered normally, and a hardfault may occur. Therefore, it is necessary to modify the circ...

How should user do with the excessive power consumption when GPIO is configured as Quasi-bidirectional mod in the M480 s

When GPIO is configured as Quasi-bidirectional mode, it consumes 65uA leakage from pull-up resister fixedly as long as the GPIO pin state is LOW. User should disable Quasi-bidirectional mode to reduce leakage current when the GPIO pin state is low. If the low state is driven by external voltage, the...
