For overrun error processing, see
Read SSR and check that the TDRE
flag is set to 1, then write transmit
data to TDR.
When data is written to TDR, the
TDRE flag is automatically cleared to
0.
Read SSR and check that the RDRF
flag is set to 1, then read the receive
data in RDR.
When data is read from RDR, the
RDRF flag is automatically cleared to
0.
To continue serial transmission/
reception, before the MSB (bit 7) of
the current frame is received, finish
reading the RDRF flag, reading RDR.
Also, before the MSB (bit 7) of the
current frame is transmitted, read 1
writing is possible. Then write data to
TDR.
When data is written to TDR, the
TDRE flag is automatically cleared to
0. When data is read from RDR, the
RDRF flag is automatically cleared to
0.
If an overrun error occurs, read the
OER flag in SSR, and after
performing the appropriate error
processing, clear the OER flag to 0.
Transmission/reception cannot be
resumed if the OER flag is set to 1.
