Interrupt fill 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.

Description
FIFO size for channel A and channel B. Selects the FIFO depth at
8-byte or 16-byte.
Bits MR0[2:0] are used to select one of the six baud rate groups. See
Table 35
Other combinations of MR0[2:0] should not be used.
0 = 8 bytes
1 = 16 bytes
000 = Normal mode
001 = Extended mode I
100 = Extended mode II
