Supported Power-down Voltage Sequence

The supported power down sequence of voltage for the processor is detailed in
Figure 2-19. It should be noted that when the processor is required to be physically
removed from its socket, power rails VCC33_SM and Vcc(12V) must also be powered
down before removal of the processor.
