To enhance reliability of serial data exchange, the serial channel ASC0 provides an error
interrupt request flag, which indicates the presence of an error, and three (selectable)
error status flags in register S0CON, which indicate which error has been detected
during reception. Upon completion of a reception, the error interrupt request flag S0EIR
will be set simultaneously with the receive interrupt request flag S0RIR, if one or more of
the following conditions are met:
• If the framing error detection enable bit S0FEN is set and any expected stop bit is not
• If the parity error detection enable bit S0PEN is set in the modes in which a parity bit
• If the overrun error detection enable bit S0OEN is set and the last character received

due to a framing error (Asynchronous mode only).

flag S0PE is set, indicating that the error interrupt request is due to a parity error
(Asynchronous mode only).
was not read out of the receive buffer by software or by PEC transfer at the time the
reception of a new frame is complete, the overrun error flag S0OE is set, indicating
that the error interrupt request is due to an overrun error (Asynchronous and
Synchronous modes).
