I'm using RT595 board Arduino header J27[1][2] J28[3][4] flexcomm12 as uart port to transfer data.
config FC12_TXD_SCL_MISO/FC12_RXD_SDA_MOSI/FC12_CTS_SDA_SSELN0/FC12_RTS_SCL_SSELN1 with IDE pin config tools and using USART_TransferStartRingBuffer
USART_TransferReceiveNonBlocking interface to receive data.
But I found RTS pin wave form is abnormal when receiving data.when zhere is data in RX pin.RTS pin will pull up each time, please help check where keeps control pulling this pin high?
for better understanding you can refers to attachment
