Section 15 Serial Communication Interface (SCI and IrDA)
Table 15.9 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 ORER,
FER, PER, and RDRF bits to 0 before resuming reception. Figure 15.9 shows a sample flow chart
for serial data reception.
