Fields

RXFIFO_FULL_THRHD

When receiver receives more data than its threshold value.receiver will produce rxfifo_full_int_raw interrupt.the threshold value is (rx_flow_thrhd_h3 rxfifo_full_thrhd).
TXFIFO_EMPTY_THRHD

when the data amount in transmitter fifo is less than its threshold value. it will produce txfifo_empty_int_raw interrupt. the threshold value is (tx_mem_empty_thrhd txfifo_empty_thrhd)
RX_FLOW_THRHD

when receiver receives more data than its threshold value. receiver produce signal to tell the transmitter stop transferring data. the threshold value is (rx_flow_thrhd_h3 rx_flow_thrhd).
RX_FLOW_EN

This is the flow enable bit for uart receiver. 1:choose software flow control with configuring sw_rts signal
RX_TOUT_THRHD

This register is used to configure the timeout value for uart receiver receiving a byte.
RX_TOUT_EN

This is the enble bit for uart receiver’s timeout function.
