Release Message Buffer
0 Buffer is free.
1 Buffer ready to be read by software. This bit must be cleared by software after reading data
received in the buffer.
This bit is cleared by hardware in Initialization mode.
FEF
Framing Error Flag
This bit is set by hardware and indicates to the software that LINFlex has detected a framing error
(invalid stop bit).
BOF
Buffer Overrun Flag
This bit is set by hardware when a new data byte is received and the buffer full flag is not cleared.
If RBLM in LINCR1 is set then the new byte received is discarded. If RBLM is reset then the new
byte overwrites buffer. it can be cleared by software.
RPS
LIN Receive Pin State
This bit reflects the current status of LINRX pin for diagnostic purposes.
WUF
Wake-up Flag
This bit is set by hardware and indicates to the software that LINFlex has detected a falling edge
on the LINRX pin in Sleep mode.
This bit must be cleared by software. It is reset by hardware in Initialization mode.
An interrupt i generated if WUIE bit in LINIER is set.
DRF
Data Reception Completed Flag
This bit is set by hardware and indicates the data reception is completed, that is, the number of
bytes programmed in RDFL[0:1] in UARTCR have been received.
This bit must be cleared by software.
It is reset by hardware in Initialization mode.
An interrupt is generated if DRIE bit in LINIER is set.
In UART mode, this flag is set in case of framing error, parity error or overrun.
DTF
Data Transmission Completed Flag
This bit is set by hardware and indicates the data transmission is completed, that is, the number of
bytes programmed in TDFL[0:1] have been transmitted.
This bit must be cleared by software.
It is reset by hardware in Initialization mode.
An interrupt is generated if DTIE bit in LINIER is set.
NF
Noise Flag
This bit is set by hardware when noise is detected on a received character. This bit is cleared by
software.
