4.6 UART1 FIFO Control Register (U1FCR - 0xE001 0008, Write Only)
4.7 UART1 Line Control Register (U1LCR - 0xE001 000C)
It is the lowest priority interrupt and is activated whenever there is any state change on
modem inputs pins, DCD, DSR or CTS. In addition, a low to high transition on modem
input RI will generate a modem interrupt. The source of the modem interrupt can be
determined by examining U1MSR[3:0]. A U1MSR read will clear the modem interrupt.
The U1FCR controls the operation of the UART1 RX and TX FIFOs.
Table 404. UART1 FIFO Control Register (U1FCR - address 0xE001 0008, Write Only) bit
The U1LCR determines the format of the data character that is to be transmitted or
received.

UART1 FIFOs are disabled. Must not be used in the application.
Active high enable for both UART1 Rx and TX FIFOs and
U1FCR[7:1] access. This bit must be set for proper UART1
operation. Any transition on this bit will automatically clear the
UART1 FIFOs.
No impact on either of UART1 FIFOs.
Writing a logic 1 to U1FCR[1] will clear all bytes in UART1 Rx
FIFO and reset the pointer logic. This bit is self-clearing.
No impact on either of UART1 FIFOs.
Writing a logic 1 to U1FCR[2] will clear all bytes in UART1 TX
FIFO and reset the pointer logic. This bit is self-clearing.
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
These two bits determine how many receiver UART1 FIFO
characters must be written before an interrupt is activated.
Trigger level 0 (1 character or 0x01).
Trigger level 1 (4 characters or 0x04).
Trigger level 2 (8 characters or 0x08).
Trigger level 3 (14 characters or 0x0E).
