9. Receiver_overflow_int

9.1. Function description:

This demo show USARTn with USARTm in overflow interrupt mode transmitter. To receive overflow interrupt, you need to configure the interrupt as overflow mode. In addition to sending busy waiting, you can send data continuously to make the received data overflow.

9.2. Test result:

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

9.3. IO connection:

PAD	PAD
pad_USART0_TX	pad_USARTm_RX
pad_USART0_RX	pad_USARTm_TX

Note

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