Name:
Access Type:
•
0 = No data has been received since the last read of RDR
1 = Data has been received and the received data has been transferred from the serializer to RDR since the last read of
RDR.
• TDRE: Transmit Data Register Empty
0 = Data has been written to TDR and not yet transferred to the serializer.
1 = The last data written in the Transmit Data Register has been transferred to the serializer.
TDRE equals zero when the SPI is disabled or at reset. The SPI enable command sets this bit to one.
• MODF: Mode Fault Error
0 = No Mode Fault has been detected since the last read of SR.
1 = A Mode Fault occurred since the last read of the SR.
• OVRES: Overrun Error Status
0 = No overrun has been detected since the last read of SR.
1 = An overrun has occurred since the last read of SR.
An overrun occurs when RDR is loaded at least twice from the serializer since the last read of the RDR.
•
0 = The Receive Counter Register has not reached 0 since the last write in RCR or RNCR.
1 = The Receive Counter Register has reached 0 since the last write in RCR or RNCR.
•
0 = The Transmit Counter Register has not reached 0 since the last write in TCR or TNCR.
1 = The Transmit Counter Register has reached 0 since the last write in TCR or TNCR.
•
0 = RCR or RNCR has a value other than 0.
1 = Both RCR and RNCR has a value of 0.
•
0 = TCR or TNCR has a value other than 0.
