LOGIC COMMANDS AND REGISTERS
Notes
63.
If CAN-INT is at logic [0], any undetermined CAN failure will be latched in the CAN register (bit D1: CAN-UF) and can be accessed by
SPI (refer to
automatically. The existence of CAN-UF always has priority over clearing, meaning that a further undetermined CAN failure does not
allow clearing the CAN-UF bit.
