    DEFINE OSC 3
    Would be for an external 3.579Mhz "Color Burst" crystal.

    If you are using the Internal Oscillator, the default on a 16F690 is 4Mhz.

    DEFINE OSC 4

    DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
    DEFINE HSER_TXSTA 20h ' Enable transmit, BRGH = 0
    DEFINE HSER_SPBRG 25 ' 2400 Baud @ 4MHz, 0.17%
    DEFINE HSER_CLROERR 1 ' Clear overflow automatically
