Silicon Labs EFM32: I want to do hardware flow control with UART, how can I do that?

EFx32

To realize hardware flow control with UART, CTS and RTS pins and their control are required, but EFM32 does not have CTS and RTS as dedicated functions. Therefore, it is necessary to use GPIO and realize it in terms of software.
We are preparing a sample code. See AN0059(UART Flow Control) for details.
