void adc_disable_clock ( ADC_t *  adc)

Disable peripheral clock for ADC.

Decrements the enable count for the ADC, then disables its peripheral clock if the count hit zero. If the count did not hit zero, it indicates the ADC is enabled.

Parameters
adcPointer to ADC module

void adc_enable_clock ( ADC_t *  adc)

Enable peripheral clock for ADC.

Checks if the enable count for the ADC is zero, then increments it. If the count was zero, the peripheral clock is enabled. Otherwise, it is already enabled.

Parameters
adcPointer to ADC module.
