Table 20.14 shows the states of the SSR status flags and receive data handling when a receive error is detected.
If a receive error is detected, an ERI interrupt request is generated but an RXI interrupt request is not generated. Data
reception cannot be resumed while the receive error flag is set to 1. Accordingly, clear the ORER, FER, and PER bits to
0 before resuming reception. Moreover, be sure to read the RDR during overrun error processing.
Figure 20.11 shows samples of flowcharts for serial data reception.
