FlexCAN
21.3.2.7 Interrupt Mask Register (IMASKn)
IMASKn contains one interrupt mask bit per buffer. It enables the CPU to determine which buffer
will generate an interrupt after a successful transmission/reception (that is, when the
corresponding IFLAGn bit is set).
21.3.2.8 Interrupt Flag Register (IFLAGn)
IFLAGn contains one interrupt flag bit per buffer. Each successful transmission/reception sets the
corresponding IFLAGn bit and, if the corresponding IMASKn bit is set, will generate an interrupt.

Error interrupt. Indicates that at least one of the ERRSTATn[15:10] bits is set. The user
must write a 1 to clear this bit. Writing 0 has no effect.
0 No error interrupt request.
1 At least one of the error bits is set. If the CANCTRLn[ERRMSK] bit is set, an interrupt
Reserved, should be cleared.
Reserved, should be cleared.
Buffer interrupt mask. Enables the respective FlexCAN message buffer (MB0 to MB15)
interrupt. These bits allow the CPU to designate which buffers will generate interrupts after
successful transmission/reception.
0 The interrupt for the corresponding buffer is disabled.
1 The interrupt for the corresponding buffer is enabled.
Note: Setting or clearing an IMASKn bit can assert or negate an interrupt request, if the
corresponding IFLAGn bit it is set.
