UART threshold and allocation configuration
RX_SIZE | This register is used to configure the amount of mem allocated for receive-FIFO. The default number is 128 bytes. |
TX_SIZE | This register is used to configure the amount of mem allocated for transmit-FIFO. The default number is 128 bytes. |
RX_FLOW_THRHD | This register is used to configure the maximum amount of data that can be received when hardware flow control works. |
RX_TOUT_THRHD | This register is used to configure the threshold time that receiver takes to receive one byte. The rxfifo_tout_int interrupt will be trigger when the receiver takes more time to receive one byte with rx_tout_en set to 1. |
MEM_FORCE_PD | Set this bit to force power down UART memory. |
MEM_FORCE_PU | Set this bit to force power up UART memory. |
