lpuart overrun interrupt

[ninghongxie]

When the lpuart is at the 1 m baud rate, the overrun interrupt will always occur。How to solve it

Hello,

I can advise some points on how to prevent overrun error:

- Decrease the BaudRate value

- Set the higher priority of LPUART interrupt

- Choose the fastest clock source for the LPUART

- You can consider using the FIFO register, see 51.3.1.12 LPUART FIFO Register (FIFO) in the RM rev. 11.

I hope it helps.

Best regards,

Diana
