RI falling edge (FERI)
DCD# toggling (TDCD)
Clear to send (CTS)
Data set ready (DSR)
Ring indicator (RI)
Data carrier detect (DCD)
CTS# toggling (TCTS)
DSR# toggling (TDSR)
Bit 7: This bit is the opposite of the DCD# input. This bit is equivalent to bit 3 of HCR in loopback
mode.
Bit 6: This bit is the opposite of the RI # input. This bit is equivalent to bit 2 of HCR in loopback
mode.
Bit 5: This bit is the opposite of the DSR# input. This bit is equivalent to bit 0 of HCR in loopback
mode.
Bit 4: This bit is the opposite of the CTS# input. This bit is equivalent to bit 1 of HCR in loopback
mode.
Bit 3: TDCD. This bit indicates that the DCD# pin has changed state after HSR was read by the CPU.
Bit 2: FERI. This bit indicates that the RI # pin has changed from low to high state after HSR was
read by the CPU.
Bit 1: TDSR. This bit indicates that the DSR# pin has changed state after HSR was read by the CPU.
Bit 0: TCTS. This bit indicates that the CTS# pin has changed state after HSR was read.
3.2.5 UART FIFO Control Register (UFR) (Write only)
This register is used to control the FIFO functions of the UART.

RX interrupt active level (LSB)
RX interrupt active level (MSB)
Bit 6, 7: These two bits are used to set the active level for the receiver FIFO interrupt. For example, if
the interrupt active level is set as 4 bytes, once there are more than 4 data characters in the
receiver FIFO, the interrupt will be activated to notify the CPU to read the data from the FIFO.
