I have uart 1 running with flow controle enabled

at32_map_usart(1, 3, ATMEL_USART_RTS | ATMEL_USART_CTS);

But the TXD and RTS line is keeping my external board from powering down correctly. Can I disable these or set them as input when I power down the external board? Or can't I reconfigure these pins?

Thanx for any replay
