16.7.5 CAN Interrupt Enable Register (CAN1IER - 0x4004 4010, CAN2IER -
[4]
Receiver Interrupt Enable. When the Receive Buffer Status is 'full', the CAN Controller
requests the respective interrupt.
Transmit Interrupt Enable for Buffer1. When a message has been successfully transmitted
out of TXB1 or Transmit Buffer 1 is accessible again (e.g. after an Abort Transmission
command), the CAN Controller requests the respective interrupt.
Error Warning Interrupt Enable. If the Error or Bus Status change (see Status Register), the
CAN Controller requests the respective interrupt.

0x4004 8010)
This read/write register controls whether various events on the CAN controller will result in
an interrupt or not. Bits 10:0 in this register correspond 1-to-1 with bits 10:0 in the
CANxICR register. If a bit in the CANxIER register is 0 the corresponding interrupt is
disabled; if a bit in the CANxIER register is 1 the corresponding source is enabled to
trigger an interrupt.
The Receive Interrupt Bit is not cleared upon a read access to the Interrupt Register. Giving the Command
“Release Receive Buffer” will clear RI temporarily. If there is another message available within the Receive
Buffer after the release command, RI is set again. Otherwise RI remains cleared.
A Wake-Up Interrupt is also generated if the CPU tries to set the Sleep bit while the CAN controller is
involved in bus activities or a CAN Interrupt is pending. The WUI flag can also get asserted when the
according enable bit WUIE is not set. In this case a Wake-Up Interrupt does not get asserted.
Whenever a bus error occurs, the corresponding bus error interrupt is forced, if enabled. At the same time,
the current position of the Bit Stream Processor is captured into the Error Code Capture Register. The
content within this register is fixed until the user software has read out its content once. From now on, the
capture mechanism is activated again, i.e. reading the CANxICR enables another Bus Error Interrupt.
On arbitration lost, the corresponding arbitration lost interrupt is forced, if enabled. At that time, the current
bit position of the Bit Stream Processor is captured into the Arbitration Lost Capture Register. The content
within this register is fixed until the user application has read out its contents once. From now on, the
capture mechanism is activated again.
Function
Each time arbitration is lost while trying to send on the CAN, the bit number
within the frame is captured into this field. After the content of ALCBIT is read,
the ALI bit is cleared and a new Arbitration Lost interrupt can occur.
arbitration lost in the first bit (MS) of identifier
arbitration lost in SRTS bit (RTR bit for standard frame messages)
arbitration lost in IDE bit
arbitration lost in 12th bit of identifier (extended frame only)
arbitration lost in last bit of identifier (extended frame only)
arbitration lost in RTR bit (extended frame only)
