• Description: High-density Complementary Metal Oxide Semiconductor (HCMOS) Microcomputer Unit
• Manufacturer: Motorola

OR — Overrun error flag
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
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.
FE — Framing error
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
PF is set if received data has incorrect parity. Clear PF by reading SCSR1 with PE set and then
reading SCDR.
