receive data stored in the receive FIFO register
(SCFRDR) is increased more than the set trigger
number shown below.

Transmit FIFO Data Trigger 1, 0
Set the quantity of remaining transmit data which sets
the transmit FIFO data register empty (TDFE) flag in the
serial status register (SCFSR). The TDFE flag is set
when the quantity of transmit data in the transmit FIFO
data register (SCFTDR) becomes less than the set
trigger number shown below.

CTS
is fixed at active 0 regardless of the input
value, and
