Table 17.6 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 17.8 shows a sample flow chart

for serial data reception.
