UART threshold and allocation configuration
RX_SIZE | This register is used to configure the amount of RAM allocated for RX FIFO. The default number is 128 bytes. |
TX_SIZE | This register is used to configure the amount of RAM allocated for TX FIFO. The default number is 128 bytes. |
RX_FLOW_THRHD | This register is used to configure the maximum amount of data bytes that can be received when hardware flow control works. |
RX_TOUT_THRHD | This register is used to configure the threshold time that the receiver takes to receive one byte, in the unit of bit time (the time it takes to transfer one bit). The UART_RXFIFO_TOUT_INT interrupt will be triggered when the receiver takes more time to receive one byte with UART RX_TOUT_EN set to 1. |
MEM_FORCE_PD | Set this bit to force power down UART RAM. |
MEM_FORCE_PU | Set this bit to force power up UART RAM. |
