Description

Wake-up Flag

This bit is set by hardware and indicates to the software that LINFlexD has detected a falling edge on

the LINRX pin when

â¢ slave is in Sleep mode,

â¢ master is in Sleep mode or idle state.

This bit must be cleared by software. It is reset by hardware in Initialization mode. An interrupt is

generated if WUIE bit in LINIER is set.

Data Buffer Full Flag

This bit is set by hardware and indicates the buffer is full. It is set only when receiving extended frames

(DFL > 7).

This bit must be cleared by software.

It is reset by hardware in Initialization mode.

Data Buffer Empty Flag

This bit is set by hardware and indicates the buffer is empty. It is set only when transmitting extended

frames (DFL > 7).

This bit must be cleared by software, once buffer has been filled again, in order to start transmission.

This bit is reset by hardware in Initialization mode.

Data Reception Completed Flag

This bit is set by hardware and indicates the data reception is completed.

This bit must be cleared by software.

It is reset by hardware in Initialization mode.

Note: This flag is not set in case of bit error or framing error.

Data Transmission Completed Flag

This bit is set by hardware and indicates the data transmission is completed.

This bit must be cleared by software.

It is reset by hardware in Initialization mode.

Note: This flag is not set in case of bit error if IOBE bit is reset.

Header Reception Flag

This bit is set by hardware and indicates a valid header reception is completed.

This bit must be cleared by software.

This bit is reset by hardware in Initialization mode and at end of completed or aborted frame.

Note: If filters are enabled, this bit is set only when identifier software filtering is required, that is to say:

â¢ all filters are inactive and BF bit in LINCR1 is set

â¢ no match in any filter and BF bit in LINCR1 is set

â¢ TX filter match
