11. Receiver_wm_int

11.1. Function description:

This demo show USARTn with USARTm in watermark timeout interrupt mode transmitter. Configure USARTm to receive as watermark timeout interrupt, send data through USARTn, and generate watermark timeout interrupt for receiving data within the specified time.

11.2. Test result:

If the USARTm watermark timeout interrupt Handler executs twice(then disable interrupt), print “pass”, if not, print “fail”.

11.3. IO connection:

PAD	PAD
pad_USARTn_TX	pad_USART1_RX
pad_USARTn_RX	pad_USART1_TX

Note

The ‘m’ and ‘n’ in “usartm” and “usartn” indicate the peripheral number.
