Section 14 Serial Communication Interface 3 (SCI3, IrDA)
Table 14.11 shows the states of the SSR status flags and receive data handling when a receive
error is detected. If a receive error is detected, the RDRF flag retains its state before receiving
data. Reception cannot be resumed while a receive error flag is set to 1. Accordingly, clear the
OER, FER, PER, and RDRF bits to 0 before resuming reception. Figure 14.8 shows a sample
flowchart for serial data reception.

The RDRF flag retains the state it had before data reception. However, note that if RDR
is read after an overrun error has occurred in a frame because reading of the receive
data in the previous frame was delayed, the RDRF flag will be cleared to 0.
