Description
Receive FIFO Interrupt Trigger Level 1, 0
These bits set the trigger level of the receive FIFO
interrupt.
00: 1 byte
01: 4 bytes
10: 8 bytes
11: 14 bytes
Reserved
These bits cannot be modified.
DMA Mode
This bit is not supported and cannot be modified.
Transmit FIFO Reset
The transmit FIFO data is cleared when 1 is written.
However, FTSR data is not cleared. This bit is
automatically cleared.
Receive FIFO Reset
The receive FIFO data is cleared when 1 is written.
However, FRSR data is not cleared.
This bit is automatically cleared.
FIFO Enable
0: Transmit/receive FIFOs disabled
1: Transmit/receive FIFOs enabled
All bytes of these FIFOs are cleared.
