-        * Description:
-        *
-        * In designs that enable and use the PLL module, unstable device
-        * behavior may occur with the LDO set at its default of 2.5 volts or
-        * below (minimum of 2.25 volts). Designs that do not use the PLL
-        * module are not affected.
-        *
-        * Workaround: Prior to enabling the PLL module, it is recommended that
-        * the default LDO voltage setting of 2.5 V be adjusted to 2.75 V using
-        * the LDO Power Control (LDOPCTL) register.

-        * Silicon Revision Affected: A1, A2

-        * See also: Stellaris LM3S1968 A2 Errata documentation.
