1.62V TO 3.63V QUAD UART WITH 32-BYTE FIFO
REV. 1.0.0
FCR[1]: RX FIFO Reset
This bit is only active when FCR bit-0 is a ‘1’.
Logic 0 = No receive FIFO reset (default)
Logic 1 = Reset the receive FIFO pointers and FIFO level counter logic (the receive shift register is not
cleared or altered). This bit will return to a logic 0 after resetting the FIFO.
FCR[2]: TX FIFO Reset
This bit is only active when FCR bit-0 is a ‘1’.
Logic 0 = No transmit FIFO reset (default).
Logic 1 = Reset the transmit FIFO pointers and FIFO level counter logic (the transmit shift register is not
cleared or altered). This bit will return to a logic 0 after resetting the FIFO.
FCR[3]: DMA Mode Select
Controls the behavior of the -TXRDY and -RXRDY pins. See DMA operation section for details.
Logic 0 = Normal Operation (default).
Logic 1 = DMA Mode.
FCR[5:4]: Transmit FIFO Trigger Select (requires EFR bit-4 = 1)
(logic 0 = default, TX trigger level = one)
These 2 bits set the trigger level for the transmit FIFO. The UART will issue a transmit interrupt when the
number of characters in the FIFO falls below the selected trigger level, or when it gets empty in case that the
FIFO did not get filled over the trigger level on last re-load. Table 12 below shows the selections.
FCR[7:6]: Receive FIFO Trigger Select
(logic 0 = default, RX trigger level =1)
These 2 bits are used to set the trigger level for the receive FIFO. The UART will issue a receive interrupt when
the number of the characters in the FIFO crosses the trigger level. Table 12 shows the complete selections.
