 *                       MSP430 CODE EXAMPLE DISCLAIMER
 *
 * MSP430 code examples are self-contained low-level programs that typically
 * demonstrate a single peripheral function or device feature in a highly
 * concise manner. For this the code may rely on the device's power-on default
 * register values and settings such as the clock configuration and care must
 * be taken when combining code from several examples to avoid potential side
 * effects. Also see www.ti.com/grace for a GUI- and www.ti.com/msp430ware
 * for an API functional library-approach to peripheral configuration.

//  MSP430x41x2 Demo - FLL+, Runs Internal DCO at 8 MHz
//
//  Description: This program demonstrates setting the internal DCO to run at
//  8MHz with auto-calibration by the FLL+ circuitry.
//  ACLK = LFXT1 = 32768Hz, MCLK = SMCLK = DCO = (121+1) x 32768 x 2 = 7.99 Mhz
//  //* An external watch crystal between XIN & XOUT is required for ACLK *//	
//
