SC16C850SV
Single UART with 128-byte FIFOs, IrDA, and XScale VLIO bus interface
7.3 FIFO Control Register (FCR)
This register is used to enable the FIFOs, clear the FIFOs and set the receive FIFO trigger
levels.

Description
FCR[7:6]
Receive trigger level in 32-byte FIFO mode.
[1]
These bits are used to set the trigger level for receive FIFO interrupt and flow
control. The SC16C850SV will issue a receive ready interrupt when the number
of characters in the receive FIFO reaches the selected trigger level. Refer to
Table 10
.
FCR[5:4]
Transmit trigger level in 32-byte FIFO mode.
[2]
These bits are used to set the trigger level for the transmit FIFO interrupt and
flow control. The SC16C850SV will issue a transmit empty interrupt when the
number of characters in FIFO drops below the selected trigger level. Refer to
Table 11
.
FCR[3]

FCR[2]
XMIT FIFO reset.
logic 0 = no FIFO transmit reset (normal default condition)
logic 1 = clears the contents of the transmit FIFO and resets the FIFO counter
logic. This bit will return to a logic 0 after clearing the FIFO.

RCVR FIFO reset.
logic 0 = no FIFO receive reset (normal default condition)
logic 1 = clears the contents of the receive FIFO and resets the FIFO counter
logic. This bit will return to a logic 0 after clearing the FIFO.
FIFO enable.
logic 0 = disable the transmit and receive FIFO (normal default condition)
logic 1 = enable the transmit and receive FIFO
