Hardware Errata
VCC_BAT errata:
Description: If VCC_BAT does not go down to 0V the processor may hang during a power-on cycle.
Workaround: Don't connect a battery or a gold cap to the VCC_BAT pin (pin 200) on the SODIMM-200 connector. In addition to that you can't buffer the date and time information.
