Description
Configures the size of the FIFO:
00 -> 16 bytes (d)
01 -> 32 bytes
10 -> 48 bytes
11 -> 64 bytes
Number of bytes to be written in the FIFO to activate the
Fifo_threshold interrupts
Actual number of bytes = B + 1, where B is the value in the register.
(d): B = 001111 => Number of bytes = 16
