13.5.2.16 CHI Error Flag Register (CHIERFR)
Write: Normal Mode
This register holds the CHI related error ags. The interrupt generation for each of these error ags is
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

Field
Description
15
FRLB_EF
Frame Lost Channel B Error Flag — This ag 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 ag 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 ag is set if the application has issued a POC command by
1. In this case the command is ignored by the FlexRay block and is lost.
0 No such error
1 POC command ignored
