PRODUCTION DATA.
The nINT is a dedicated open drain global interrupt output pin. This pin needs an external pull-up resistor to VIO to function properly. All interrupt requests are reflected by this pin when pulled low.
In test mode, this pin is used as an EN pin input for testing the CAN transceiver and is shown as EN_INT throughout the document. When this pin is high, the device is in normal mode and when low it is in standby mode. This is accomplished by writing 0 to register 16'h0800[0].
NOTE
This pin is an active low and is the logical OR of all faults in registers 16'h0820 and 16'h0824 that are not masked.
