-	 *
-	 * 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.
