25.7.16 LIN Mode Register
Name: LINMR
Access Type: Read-write
Offset: 0x54
Reset Value: 0x00000000
• PDCM: Peripheral DMA Controller Mode
0: The LIN mode register is not written by the Peripheral DMA Controller.
1: The LIN mode register, except for this bit, is written by the Peripheral DMA Controller.
• DLC: Data Length Control
0 - 255: If DLM=0 this field defines the response data length to DLC+1 bytes.
• WKUPTYP: Wakeup Signal Type
0: Writing a one to CR.LINWKUP will send a LIN 2.0 wakeup signal.
1: Writing a one to CR.LINWKUP will send a LIN 1.3 wakeup signal.
• FSDIS: Frame Slot Mode Disable
0: The Frame Slot mode is enabled.
1: The Frame Slot mode is disabled.
• DLM: Data Length Mode
0: The response data length is defined by DLC.
1: The response data length is defined by bits 4 and 5 of the Identifier (LINIR.IDCHR).
• CHKTYP: Checksum Type
0: LIN 2.0 “Enhanced” checksum
1: LIN 1.3 “Classic” checksum
• CHKDIS: Checksum Disable
0: Checksum is automatically computed and sent when master, and checked when slave.
1: Checksum is not computed and sent, nor checked.
• PARDIS: Parity Disable
0: Identifier parity is automatically computed and sent when master, and checked when slave.
1: Identifier parity is not computed and sent, nor checked.
