Table 58. UART Interrupt Status Codes (Continued)
UART FIFO Control Register
This register is used to monitor trigger levels, clear FIFO pointers, and enable or disable
the FIFO. The UARTx_FCTL registers share the same I/O addresses as the UARTx_IIR
registers. See
Table 59. UART FIFO Control Registers(UART0_FCTL = 00C2h, UART1_FCTL =
00D2h)

Description
Receive FIFO trigger level set to 1. Receive data interrupt is
generated when there is 1 byte in the FIFO. Valid only if FIFO
is enabled.
Receive FIFO trigger level set to 4. Receive data interrupt is
generated when there are 4 bytes in the FIFO. Valid only if
FIFO is enabled.
Receive FIFO trigger level set to 8. Receive data interrupt is
generated when there are 8 bytes in the FIFO. Valid only if
FIFO is enabled.
Receive FIFO trigger level set to 14. Receive data interrupt is
generated when there are 14 bytes in the FIFO. Valid only if
FIFO is enabled.
Reserved.
No effect.
Clear the transmit FIFO and reset the transmit FIFO pointer.
Valid only if the FIFO is enabled.
