Figure 26-15. CHI Error Flag Register (CHIERFR)
This register holds the CHI related error flags. The interrupt generation for each of these error flags is
controlled by the CHI interrupt enable bit CHIE in the Global Interrupt Flag and Enable Register (GIFER).

Field
FRLB_EF
FRLA_EF
Description
Frame Lost Channel B Error Flag — This flag is set if a complete frame was received on channel B but could
not be stored in the selected individual message buffer because this message buffer is currently locked by the
application. In this case, the frame and the related slot status information are lost.
0 No such event.
1 Frame lost on channel B detected.
Frame Lost Channel A Error Flag — This flag is set if a complete frame was received on channel A but could
not be stored in the selected individual message buffer because this message buffer is currently locked by the
application. In this case, the frame and the related slot status information are lost.
0 No such error.
1 Frame lost on channel A detected.
