3.3 V/5.0 V Dual Universal Asynchronous Receiver/Transmitter
[1]
Interrupt ll level must be set when the transmit and receive FIFOs are empty, otherwise the new level takes
effect only after a read or a write to the FIFO.

FIFOSIZE
FIFO size for channel A and channel B. Selects the FIFO depth at
8-byte or 16-byte.
0 = 8 bytes
1 = 16 bytes

BAUDRATE
EXTENDED I
Bits MR0[2:0] are used to select one of the six baud rate groups. See
Table 35 for the group organization.
000 = Normal mode
001 = Extended mode I
100 = Extended mode II
Other combinations of MR0[2:0] should not be used.
