OR — Overrun error flag
1 (set) – Overrun detected.
0 (clear) – No overrun.
OR is set if a new character is received before a previously received character is read from SCDR.
Clear the OR flag by reading SCSR1 with OR set and then reading SCDR.
NF — Noise error flag
1 (set) – Noise detected.
0 (clear) – Unanimous decision.
NF is set if the majority sample logic detects anything other than a unanimous decision. Clear NF
by reading SCSR1 with NF set and then reading SCDR.
5
FE — Framing error
1 (set) – Zero detected.
0 (clear) – Stop bit detected.
FE is set when a zero is detected where a stop bit was expected. Clear the FE flag by reading
SCSR1 with FE set and then reading SCDR.
PF — Parity error flag
1 (set) – Incorrect parity detected.
0 (clear) – Parity correct.
PF is set if received data has incorrect parity. Clear PF by reading SCSR1 with PE set and then
reading SCDR.
