Notes
1. To avoid a ‘latch up’ effect at power-on: VSS − 0.5 V < ‘voltage on any pin at any time’ < VDD + 0.5 V.
2. If the CAN-controller is in the reset state (e.g. after a power-up reset; CAN Control Register bit CR.0; see
Section 13.5.3 Table 32), the CAN transmitter outputs are floating and the pins P1.6 and P1.7 can be used as
open-drain port pins. After a power-up reset the port data is HIGH, leaving the pins P1.6 and P1.7 floating.
