29.3.4 Error Interrupts

The following error detection features are supported with Interrupt by the SCI module:

• Parity errors (PE)

• Frame errors (FE)

• Break Detect errors (BRKDT)

• Overrun errors (OE)

If any of these errors (PE, FE, BRKDT, OE) is 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. Further

details on these flags are explained in SCIFLR register description.

The SCI module supports following 7 interrupts as seen in Table 29-1.
