mbed_official 155:8435094ec241 1733 avoids the loss of the data already stored in the ADC Data register.

mbed_official 155:8435094ec241 2098 The user should identify which mode will be used in his application to manage
mbed_official 155:8435094ec241 2099 the ADC controller events: Polling mode or Interrupt mode.
mbed_official 155:8435094ec241 2100
mbed_official 155:8435094ec241 2101 In the Polling Mode it is advised to use the following functions:
mbed_official 155:8435094ec241 2102 - ADC_GetFlagStatus() : to check if flags events occur.
mbed_official 155:8435094ec241 2103 - ADC_ClearFlag() : to clear the flags events.
mbed_official 155:8435094ec241 2104
mbed_official 155:8435094ec241 2105 In the Interrupt Mode it is advised to use the following functions:
mbed_official 155:8435094ec241 2106 - ADC_ITConfig() : to enable or disable the interrupt source.
mbed_official 155:8435094ec241 2107 - ADC_GetITStatus() : to check if Interrupt occurs.
mbed_official 155:8435094ec241 2108 - ADC_ClearITPendingBit() : to clear the Interrupt pending Bit
mbed_official 155:8435094ec241 2109 (corresponding Flag).
