DSF

Double Stop Flags. When a bit error has been detected, this will add an additional stop flag to the byte in

which the error occurred.

PRTY

Activating Parity Generation. Generate the two Parity Bits in the LIN header.

LIN

LIN Mode. Switch device into LIN mode.

Note: In LIN mode data transfer should be done only via the LIN interface. The SBK bit (in SCICR2) and

the SCI data registers (SCIDRH/L) should not be used. Similarly all data transfer handshaking

should be done via the LIN interface, the TDRE, TC and RDRF flags in the SCISR1 should not be

used for that purpose.

Address Offset: 0xD

Access: User read/write (with no ongoing transmissions)

Description

RXIE

LIN RXREG Ready Interrupt Enable. Generates an Interrupt when new data is available in the LIN

RXREG.

TXIE

LIN TXREG Ready Interrupt Enable. Generates an Interrupt when new data can be written to the LIN

TXREG.

WUIE

RX WakeUP Interrupt Enable. Generates an Interrupt when a wakeup flag from a LIN 1.x slave has been

received. When using this feature the guidelines in Section 31.10.11.5, “LIN Wakeup,” should be followed.

STIE

Slave Timeout Error Interrupt Enable. Generates an Interrupt when the slave response is too slow.

PBIE

Physical Bus Error Interrupt Enable. Generates an Interrupt when no valid message can be generated on

the bus.

CIE

CRC Error Interrupt Enable. Generates an Interrupt when a CRC error on a received extended frame is

detected.

CKIE

Checksum Error Interrupt Enable. Generates an Interrupt on a detected Checksum Error.

FCIE

Frame Complete Interrupt Enable. Generates an Interrupt after complete transmission of a TX frame, or

after the last byte of an RX frame is received. (The complete frame includes all header, data, CRC and

checksum bytes as applicable.)
