31.8.16 USART3 LIN Mode Register
Name: US_LINMR
Access: Read-write
•NACT: LIN Node Action
• PARDIS: Parity Disable
0: In Master node configuration, the Identifier Parity is computed and sent automatically. In Master node and Slave node
configuration, the parity is checked automatically.
1:Whatever the node configuration is, the Identifier parity is not computed/sent and it is not checked.
• CHKDIS: Checksum Disable
0: In Master node configuration, the checksum is computed and sent automatically. In Slave node configuration, the check-
sum is checked automatically.
1: Whatever the node configuration is, the checksum is not computed/sent and it is not checked.
• CHKTYP: Checksum Type
0: LIN 2.0 “Enhanced” Checksum
1: LIN 1.3 “Classic” Checksum
• DLM: Data Length Mode
0: The response data length is defined by the field DLC of this register.
1: The response data length is defined by the bits 5 and 6 of the Identifier (IDCHR in US_LINIR).
• FDIS: Frame Slot Mode Disable
0: The Frame Slot Mode is enabled.
1: The Frame Slot Mode is disabled.
• WKUPTYP: Wakeup Signal Type
0: setting the bit LINWKUP in the control register sends a LIN 2.0 wakeup signal.
