3. Data based on a differential IDD measurement between reset configuration (CAN disabled) and a permanent CAN data
transmit sequence in loopback mode at 1 MHz. This measurement does not include the pad toggling consumption.
4. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
