21.3.6
SCSCR is a register used to enable/disable transmission/reception by SCIF, serial clock output,
interrupt requests, and to select transmission/reception clock source for the SCIF.
SCSCR can always be read from and written to by the CPU.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Transmit Interrupt Enable
Enables or disables transmit-FIFO-data-empty interrupt
(TXI) request generation when serial transmit data is
transferred from SCFTDR to SCTSR, the number of
data bytes in SCFTDR falls to or below the transmit
trigger set number, and the TDFE flag in SCFSR is set
to 1.
TXI interrupt requests can be cleared using the
following methods: Either by reading 1 from the TDFE
flag in SCFSR, writing transmit data exceeding the
transmit trigger set number to SCFTDR and then
clearing the TDFE flag in SCFSR to 0, or by clearing
the TIE bit to 0.
0: Transmit-FIFO-data-empty interrupt (TXI) request
1: Transmit-FIFO-data-empty interrupt (TXI) request
