Table 12.11 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
ORER, FER, PER, and RDRF bits to 0 before resuming reception. Figure 12.9 shows a sample
flowchart for serial data reception.
