SCI initialization: the receive data function of
the RxD pin is selected automatically.
detection: if a receive error occurs, read the
ORER, PER, and FER flags in SSR to identify
the error. After executing the necessary error
handling, clear the ORER, PER, and FER
flags all to 0. Receiving cannot resume if any
of the ORER, PER, and FER flags remains
set to 1. When a framing error occurs, the
RxD pin can be read to detect the break state.
SCI status check and receive data read: read
SSR, check that RDRF 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.
To continue receiving serial data: check the
RDRF flag, read RDR, and clear the RDRF
flag to 0 before the stop bit of the current
frame is received. If the DMAC is activated
by an RXI interrupt to read the RDR value,
the RDRF flag is cleared automatically.
