Description
Receive Message Buffer Interrupt Flag â This ï¬ag is set if for at least one of the individual receive message
buffers (MBCCSn.MTD = 0) both the interrupt ï¬ag MBIF and the interrupt enable bit MBIE in the corresponding
Message Buffer Conï¬guration, Control, Status Registers (MBCCSRn) are asserted. The application can not
clear this RBIF ï¬ag directly. This ï¬ag is cleared by the FlexRay block when all of the interrupt ï¬ags 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 ï¬ag asserted.
1 At least one individual receive message buffer has the MBIF and MBIE ï¬ag asserted.
Transmit Buffer Interrupt Flag â This ï¬ag is set if for at least one of the individual single or double transmit
message buffers (MBCCSn.MTD = 0) both the interrupt ï¬ag MBIF and the interrupt enable bit MBIE in the
corresponding Message Buffer Conï¬guration, Control, Status Registers (MBCCSRn) are equal to 1. The
application can not clear this TBIF ï¬ag directly. This ï¬ag is cleared by the FlexRay block when either all of the
individual interrupt ï¬ags 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 ï¬ag asserted.
1 At least one individual transmit message buffer has the MBIF and MBIE ï¬ag asserted.
Module Interrupt Enable â This ï¬ag controls if the module interrupt line is asserted when the MIF ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
Protocol Interrupt Enable â This ï¬ag controls if the protocol interrupt line is asserted when the PRIF ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
CHI Interrupt Enable â This ï¬ag controls if the CHI interrupt line is asserted when the CHIF ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
Wakeup Interrupt Enable â This ï¬ag controls if the wakeup interrupt line is asserted when the WUPIF ï¬ag is
set.
0 Disable interrupt line
1 Enable interrupt line
Receive FIFO channel B Not Empty Interrupt Enable â This ï¬ag controls if the receive FIFO B interrupt line
is asserted when the FNEBIF ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
Receive FIFO channel A Not Empty Interrupt Enable â This ï¬ag controls if the receive FIFO A interrupt line
is asserted when the FNEAIF ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
Receive Buffer Interrupt Enable â This ï¬ag controls if the receive buffer interrupt line is asserted when the
RBIF ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
Transmit Interrupt Enable â This ï¬ag controls if the transmit buffer interrupt line is asserted when the TBIF
ï¬ag is set.
0 Disable interrupt line
1 Enable interrupt line
