== Hardware Errata ==
== Available Documents from Freescale ==
  VCC_BAT errata:
    Description: If VCC_BAT does not go down to 0V the processor may hang during 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.
  Affected serial numbers:
    1164AA KA11.0328 ... (DH HW Version 406-200)
    11641A KA11.0328 ... (DH HW Version 406-200)


  SPI Flash errata:

    Description: Boot from SPI Flash is not possible, because the wrong CS is connected to the serial flash memory.
    Workaround: -
  Affected serial numbers:
    1164AA KA11.0328 ... (DH HW Version 406-200)
    11641A KA11.0328 ... (DH HW Version 406-200)
 
  UART1 CTS and RTS errata:
    Description: DHCOM UART1_CTS and UART1_RTS inverted.
    Workaround: Don't use hardware flow control.
  Affected serial numbers:
    1164AA KA11.0328 ... (DH HW Version 406-200)
    11641A KA11.0328 ... (DH HW Version 406-200)
