    reducing current consumption
    240x DSPs incorporate a unique method to reduce the device current consumption. A reduction in current
    consumption can be achieved by turning off the clock to any peripheral module which is not used in a given
    application. Table 17 indicates the typical reduction in current consumption achieved by turning off the clocks
    to various peripherals. Refer to the
    TMS320LF/LC240xA DSP Controllers Reference Guide: System and
    Peripherals
    (literature number SPRU357) for further information on how to turn off the clock to the peripherals.

    This number represents the current drawn by the digital portion of the ADC module.
    Turning off the clock to the ADC module results in the elimination of the current drawn
    by the analog portion of the ADC (ICCA) as well.
