CHI Error Flag Register (CHIERFR)
This register holds the CHI related error flags. The application can clear each error flag by writing a 1 to
it. Writing a 0 does not change the state of the flag. 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
11–8
SSI[3:0]_IE
Slot Status Counter Incremented Interrupt Enable — This bit controls SSI[3:0]_IF interrupt request
generation.
0 interrupt request generation disabled
1 interrupt request generation enabled
5
EVT_IE
Even Cycle Table Written Interrupt Enable — This bit controls EVT_IF interrupt request generation.
0 interrupt request generation disabled
1 interrupt request generation enabled
4
ODT_IE
Odd Cycle Table Written Interrupt Enable — This bit controls ODT_IF interrupt request generation.
0 interrupt request generation disabled
1 interrupt request generation enabled

Description
15
FRLB_EF
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
14
FRLA_EF
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
13
PCMI_EF
Protocol Command Ignored Error Flag — This flag is set if the application has issued a POC command by
writing to the POCCMD field in the
Protocol Operation Control Register (POCR)
while the BSY flag is equal to
1. In this case the command is ignored by the FlexRay module and is lost.
0 No such error
1 POC command ignored
