• Manufacturer: Freescale Semiconductor, Inc

11-sint
OR — Overrun Error Flag
NF — Noise Error Flag
FE — Framing Error Flag
PF — Parity Error Flag
New byte is ready to be transferred from the receive shift register to
the receive data register and the receive data register is already full
(RDRF bit is set). Data transfer is inhibited until this bit is cleared.
Set during the same cycle as the RDRF bit but not set in the case of
an overrun (OR).
Set when a zero is detected where a stop bit was expected. Clear the
FE flag by reading SC0SR1 with FE set and then reading SC0DR.
Indicates if received data’s parity matches parity bit. This feature is
active only when parity is enabled. The type of parity tested for is
determined by the PT (parity type) bit in SC0CR1.

For More Information On This Product,
0 = No overrun
1 = Overrun detected
0 = Unanimous decision
1 = Noise on a valid start bit, any of the data bits, or on the stop bit
0 = Stop bit detected
1 = Zero detected rather than a stop bit
0 = Parity correct
1 = Incorrect parity detected
