Table 15.12 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 15.12 shows a sample

flowchart for serial data reception.
