PIC16F870/871 - What is the restart procedure after frame error (FERR) event ?

What is the restart procedure for PIC16F870 / PIC16F871, after the frame error (FEER) event?

Framing error bit (FERR) and RCSTA is set if a STOP bit is detected as clear. The FERR bit and the ninth receive bit are buffered the same way as the receive data. Reading the RCREG loads bits RX9D and FERR with new values, therefore, it is essential for you to read the RCSTA register before reading the RCREG register in order not to lose the old FERR and RX9D information.
