    There are open source code examples for MSP430G2553

    http://www.ti.com/lit/zip/slac485

    And there is msp430g2xx3_dco_flashcal.c file inside zip, where any DCO you want can be stored in device.

    #define DELTA_1MHZ    244                   // 244 x 4096Hz = 999.4Hz
    #define DELTA_8MHZ    1953                  // 1953 x 4096Hz = 7.99MHz
    #define DELTA_12MHZ   2930                  // 2930 x 4096Hz = 12.00MHz
    #define DELTA_16MHZ   3906                  // 3906 x 4096Hz = 15.99MHz
