The interrupt register allows the identification of an interrupt source. When one or more bits of this register are set, a CAN
interrupt will be indicated to the CPU. After this register is read by the CPU all bits are reset except for the receive interrupt
bit.
The interrupt register appears to the CPU as a read only memory.

set; this bit is set when the CAN controller detects
an error on the CAN-bus and the BEIE bit is set
within the interrupt enable register
reset
set; this bit is set when the CAN controller lost the
arbitration and becomes a receiver and the ALIE
bit is set within the interrupt enable register
reset
set; this bit is set whenever the CAN controller has
reached the error passive status (at least one
error counter exceeds the protocol-defined level of
127) or if the CAN controller is in the error passive
status and enters the error active status again and
the EPIE bit is set within the interrupt enable
register
reset
set; this bit is set when the CAN controller is
sleeping and bus activity is detected and the
WUIE bit is set within the interrupt enable register
reset
set; this bit is set on a ‘0-to-1’ transition of the data
overrun status bit and the DOIE bit is set within
the interrupt enable register
reset
set; this bit is set on every change (set and clear)
of either the error status or bus status bits and the
EIE bit is set within the interrupt enable register
reset
set; this bit is set whenever the transmit buffer
status changes from ‘0-to-1’ (released) and the
TIE bit is set within the interrupt enable register
reset
set; this bit is set while the receive FIFO is not
empty and the RIE bit is set within the interrupt
enable register
reset; no more message is available within the
RXFIFO
