Serial Communication Interface (SCI)/ Local Interconnect Network (LIN)
Module
29.2.2.4 Error Interrupts
The following error detection are supported with Interrupt by the SCI module:
• Parity errors (PE)
• Frame errors (FE)
• Break Detect errors (BRKDT)
• Overrun errors (OE)
• Bit errors (BE)
If all of these errors (PE, FE, BRKDT, OE, BE) are flagged, an interrupt for the flagged errors will be
generated if enabled. A message is valid for both the transmitter and the receiver if there is no error
detected until the end of the frame. Each of these flags is located in the receiver status (SCIFLR) register.
There are 16 interrupt sources in the SCI/LIN module, In SCI mode 8 interrupts are supported, as seen in
Table 29-4.
(1)
Offset 1 is the highest priority. Offset 16 is the lowest priority.
