Before switching transmission mode (TE = 1) or reception mode (RE = 1) to
transmission/reception mode (TE = RE = 1), clear the TE and RE bits to 0. When starting the
transfer, confirm that the TEND, RDRF, and ORER bits are cleared to 0 before setting the TE or
RE bits to 1.

[5] Procedure for consecutive data transmission/reception:
Specify the transmit/receive data format.
Write transmit data to SSTDR after reading and
confirming that the TDRE bit in SSSR is 1. The TDRE bit
is automatically cleared to 0 and transmission is started
by writing data to SSTDR.
Read SSSR confirming that the RDRF bit is 1.
A change of the RDRF bit (from 0 to 1) can be notified
by RXI interrupt.
When a receive error occurs, execute the designated
error processing after reading the ORER bit in SSSR.
After that, clear the ORER bit to 0. While the ORER bit is
set to 1, transmission or reception is not resumed.
To continue serial data transmission/reception, confirm
that the TDRE bit is 1 meaning that SSTDR is ready to be
written to. After that, data can be written to SSTDR. The
TDRE bit is automatically cleared to 0 by writing data to
SSTDR.
