Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Transmit FIFO Threshold Level
Controls the level of entries (or below) that trigger
the TX_EMPTY interrupt (bit 4 in IC_RAW_INTR_STAT register).
The valid range is 0-255, with the additional restriction that
it may not be set to value larger than the depth of the buffer.
If an attempt is made to do that, the actual value set will be
the maximum depth of the buffer (64).
A value of 0 sets the threshold for 0 entries, and a value of 255
sets the threshold for 255 entries.
