[3] To output a break at the end of serial transmission, set the
data to FTHR. When FIFOs are used, write 1-byte to 16-byte
transmit data. When the OUT2 bit in FMCR and the ETBEI bit
in FIER are set to 1, an FTHR empty interrupt occurs. When
data is written to FTHR, it is transferred automatically to FTSR.
The data is then transmitted from the FTxD pin in the order of
the start bit, transmit data, parity bit, and stop bit.
1 to ensure that all transmit data has been transmitted.
BREAK bit in FLCR to 1. After completion of the break time,
clear the BREAK bit in FLCR to 0 to clear the break.
