Table 3-3 :  CAN Control Register 

After power-up or board reset the CAN controllers are set to reset mode. 
To set the CAN controllers to operating mode, the CANx_RST# bit must be set to ‘1’. 

After power-up or board reset the CAN bus transceivers are set to silent mode. 
To set the CAN bus transceivers to operating mode, the CANx_SEL bit must be set to ‘1’. 

Disabling interrupts in the CAN Control Register only affects the interrupt mapping to the 
PCI9030 LINTx# local interrupt inputs. It will not affect the interrupt source of the SJA1000 CAN 
controllers. 

If enabled, the CAN CH1 interrupt source is mapped to the PCI9030 LINT1# local interrupt input. 
If enabled, the CAN CH2 interrupt source is mapped to the PCI9030 LINT2# local interrupt input. 
The PCI9030 LINTx# local interrupt inputs are used in active low level sensitive mode. 
 
The CAN interrupts must be acknowledged via SJA1000 registers (CAN Controller Register 
Space). 
Please see the SJA1000 CAN Controller Manual for more information.
