ORER, PER, and FER flags are cleared to 0. If the FER or PER flag is set to 1 the RDRF flag
will not be set and both transmitting and receiving will be disabled.

occurs, read the ORER flag in SSR, then
after executing the necessary error
handling, clear the ORER flag to 0. Neither
transmitting nor receiving can resume
while the ORER flag remains set to 1.
read SSR, check that the RDRF flag is set
to 1, then read receive data from RDR and
clear the RDRF flag to 0. Notification that
the RDRF flag has changed from 0 to 1 can
also be given by the RXI interrupt.

flag to 0 before the MSB (bit 7) of the
current frame is received. If the DMAC is
activated by a receive-data-full interrupt
request (RXI) to read RDR, the RDRF flag
is cleared automatically.
