Note
1. The receive interrupt enable bit has direct influence to the receive interrupt bit and the external interrupt output INT.
6.4.8
This register contains information about the bit position of losing arbitration. The arbitration lost capture register appears
to the CPU as a read only memory. Reserved bits are read as logic 0.
Table 17 Bit interpretation of the arbitration lost capture register (ALC); CAN address 11
On arbitration lost, the corresponding arbitration lost interrupt is forced, if enabled. At the same 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 users software has read out its contents once. The capture mechanism is then activated again.
The corresponding interrupt flag located in the interrupt register is cleared during the read access to the interrupt register.
A new arbitration lost interrupt is not possible until the arbitration lost capture register is read out once.
