• Manufacturer: Advanced Micro Devices

Bit 5: Framing Error Detected (FER)—When this bit is set, the serial port has detected a
framing error. Framing errors are generated when the receiver samples the RXD line as
Low when it expected the stop bit .
Note: This bit should be reset by software.
Bit 4: Overrun Error Detected (OER)—This bit is set when the processor detects an
overrun error. An overrun error occurs when the serial port overwrites valid, unread data
in the receive register, resulting in loss of data.
Note: This bit should be reset by software.
Bit 3: Parity Error Detected (PER)—This bit is set when the processor detects a parity
error (modes 1 and 3).
Note: This bit should be reset by software.
Bit 2: Transmitter Empty (TEMT)—When this bit is set, the transmitter has no data to
transmit and the transmit shift register is empty. This indicates to software that it is safe to
disable the transmit section. This bit is read-only .
Bit 1: Handshake Signal 0 (HS0)—This bit reflects the inverted value of the external CTS
pin. If CTS is asserted, HS0 is set to 1. This bit is read-only.
Bit 0: Reserved
10-10
