Bits 23:16 – RXCHK[7:0] Receive Checksum bits (calculated from RX words)
LIN Modes:
C0EN = 1: Sum of all received data + addition carries, including
PID.
C0EN = 0: Sum of all received data + addition carries, excluding
PID.
LIN Responder:
Cleared when Break is detected.
LIN Commander/Responder:
Cleared when Break is detected.
Other Modes:
C0EN = 1: Sum of every byte received + addition carries
C0EN = 0: Value remains unchanged.
Bits 7:0 – TXCHK[7:0] Transmit Checksum bits (calculated from TX words)
LIN Modes:
C0EN = 1: Sum of all transmitted data + addition carries,
including PID
C0EN = 0: Sum of all transmitted data + addition carries,
excluding PID
LIN Responder:
Cleared when Break is detected.
LIN Commander/Responder:
Cleared when Break is detected.
Other Modes:
C0EN = 1: Sum of every byte transmitted + addition carries
C0EN = 0: Value remains unchanged.
