I have a quetion about UART of AM335x.
I'd like to do FIFO setting of UART as follows here.
* Without DMA use.
* A threshold of TxFIFO and RxFIFO is 1 byte.
It's established as follows at present, but would this setting be right ?
*UART_SCR [7:6] = 11b (I cut in and set the trigger level as 1 byte unit.)
*UART_TLR [7:4] = 0000b, UART_FCR [7:6] = 01b (of the RxFIFO trigger level, 1 byte)
*UART_TLR [3:0] = 0000b, UART_FCR [5:4] = 01b (of the TxFIFO trigger level, 1 byte)
*UART_SCR[0] = 0b, UART_FCR[3] = 0b, UART_FCR[0] = 1b(FIFO effectively, DMA invalidity)
Best regards.
