FlexRay Module (FLEXRAYV2)
3.4.19.1.5
The FlexRay module provides 16 interrupt sources for CHI related error events. For details, see
Flag Register
interrupt sources.
3.4.19.2
Each combined interrupt source generates an interrupt request only when at least one of the interrupt
sources that is combined generates an interrupt request.
3.4.19.2.1
The combined receive message buffer interrupt request RBIRQ is generated when at least one of the
individual receive message buffers generates an interrupt request MBXIRQ[n] and the interrupt enable bit
GIFER.RBIE is set.
3.4.19.2.2
The combined transmit message buffer interrupt request TBIRQ is generated when at least one of the
individual transmit message buffers generates an interrupt request MBXIRQ[n] and the interrupt enable
bit GIFER.TBIE is asserted.
3.4.19.2.3
The combined protocol interrupt request PRTIRQ is generated when at least one of the individual protocol
interrupt sources generates an interrupt request and the interrupt enable bit GIFER.PRIE is set.
3.4.19.2.4
The combined CHI error interrupt interrupt request CHIIRQ is generated when at least one of the
individual chi error interrupt sources generates an interrupt request and the interrupt enable bit
GIFER.CHIE is set.
3.4.19.2.5
The combined module interrupt request MIRQ is generated if at least one of the combined interrupt
sources generates an interrupt request and the interrupt enable bit GIFER.MIE is set.
