RBIF
Receive Message Buffer Interrupt Flag — This flag is set if for at least one of the individual receive message
buffers (MBCCSn.MTD = 0) both the interrupt flag MBIF and the interrupt enable bit MBIE in the corresponding
Message Buffer Configuration, Control, Status Registers (MBCCSRn)
are asserted. The application can not
clear this RBIF flag directly. This flag is cleared by the FlexRay module when all of the interrupt flags MBIF of
the individual receive message buffers are cleared by the application or if the application has cleared the
interrupt enables bit MBIE.
0 None of the individual receive message buffers has the MBIF and MBIE flag asserted.
1 At least one individual receive message buffer has the MBIF and MBIE flag asserted.
8
TBIF
Transmit Buffer Interrupt Flag — This flag is set if for at least one of the individual single or double transmit
message buffers (MBCCSn.MTD = 0) both the interrupt flag MBIF and the interrupt enable bit MBIE in the
corresponding
Message Buffer Configuration, Control, Status Registers (MBCCSRn)
are equal to 1. The
application can not clear this TBIF flag directly. This flag is cleared by the FlexRay module when all of the
individual interrupt flags MBIF of the individual transmit message buffers are cleared by the application or the
host has cleared the interrupt enables bit MBIE.
0 None of the individual transmit message buffers has the MBIF and MBIE flag asserted.
1 At least one individual transmit message buffer has the MBIF and MBIE flag asserted.
7
MIE
Module Interrupt Enable — This flag controls if the module interrupt line is asserted when the MIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
6
PRIE
Protocol Interrupt Enable — This flag controls if the protocol interrupt line is asserted when the PRIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
5
CHIE
CHI Interrupt Enable — This flag controls if the CHI interrupt line is asserted when the CHIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
4
WUPIE
Wakeup Interrupt Enable — This flag controls if the wakeup interrupt line is asserted when the WUPIF flag is
set.
0 Disable interrupt line
1 Enable interrupt line
3
FNEBIE
Receive FIFO channel B Not Empty Interrupt Enable — This flag controls if the receive FIFO B interrupt line
is asserted when the FNEBIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
2
FNEAIE
Receive FIFO channel A Not Empty Interrupt Enable — This flag controls if the receive FIFO A interrupt line
is asserted when the FNEAIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
1
RBIE
Receive Buffer Interrupt Enable — This flag controls if the receive buffer interrupt line is asserted when the
RBIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
0
TBIE
Transmit Interrupt Enable — This flag controls if the transmit buffer interrupt line is asserted when the TBIF
flag is set.
0 Disable interrupt line
1 Enable interrupt line
