62 / 168 page  (2) I2C3_SCL is implemented with the typical LVCMOS voltage buffer and should be properly configured to operate as an Input/Output Open Drain signal type. Note I2C signals that are implemented on an LVCMOS voltage buffer pin can be configured to operate as open-drain outputs by configuring the I2C module to source a constant low output and toggle the output enable. The output buffer drives low when enabled and is high impedance when disabled. The (I2C OD FS) are the only IO voltage buffers which are fail-safe. These are implemented for I2C0 pins only. Other IOs do not allow any potential greater than (VDD + 0.3V) to be applied. This means you can not source any potential to these pins when power is off. All attached devices that can source a potential to these IOs must be powered from the same power supply that is sourcing the respective IO power rail. 5.3.13 LIN Table 5-70.
