mbed_official	76:aeb1df146756	735	subsection provides functions allowing to configure the ADC regular
mbed_official	76:aeb1df146756	736	channels :
mbed_official	76:aeb1df146756	737	(++) Configure the rank in the regular group sequencer for each channel.
mbed_official	76:aeb1df146756	738	(++) Configure the sampling time for each channel.
mbed_official	76:aeb1df146756	739	(++) select the conversion Trigger for regular channels.
mbed_official	76:aeb1df146756	740	(++) select the desired EOC event behavior configuration.
mbed_official	76:aeb1df146756	741	(++) Activate the continuous Mode (*).
mbed_official	76:aeb1df146756	742	(++) Activate the Discontinuous Mode.
mbed_official	76:aeb1df146756	743	-@@- Please Note that the following features for regular channels are
mbed_official	76:aeb1df146756	744	configurated using the ADC_Init() function :
mbed_official	76:aeb1df146756	745	(+@@) scan mode activation.

mbed_official	76:aeb1df146756	750	-@@- () and (*) are performing the same configuration.
mbed_official	76:aeb1df146756	751	(#) Get the conversion data: This subsection provides an important function
mbed_official	76:aeb1df146756	752	in the ADC peripheral since it returns the converted data of the current
mbed_official	76:aeb1df146756	753	regular channel. When the Conversion value is read, the EOC Flag is

mbed_official	76:aeb1df146756	1149	===============================================================================
mbed_official	76:aeb1df146756	1150	[..] This section provides functions allowing to configure the DMA for ADC regular
mbed_official	76:aeb1df146756	1151	channels.Since converted regular channel values are stored into a unique
mbed_official	76:aeb1df146756	1152	data register, it is useful to use DMA for conversion of more than one
mbed_official	76:aeb1df146756	1153	regular channel. This avoids the loss of the data already stored in the
mbed_official	76:aeb1df146756	1154	ADC Data register.
mbed_official	76:aeb1df146756	1155	When the DMA mode is enabled (using the ADC_DMACmd() function), after each
mbed_official	76:aeb1df146756	1156	conversion of a regular channel, a DMA request is generated.
mbed_official	76:aeb1df146756	1157	[..] Depending on the "DMA disable selection" configuration (using the
mbed_official	76:aeb1df146756	1158	ADC_DMARequestAfterLastTransferCmd() function), at the end of the last DMA
mbed_official	76:aeb1df146756	1159	transfer, two possibilities are allowed:
mbed_official	76:aeb1df146756	1160	(+) No new DMA request is issued to the DMA controller (feature DISABLED).
mbed_official	76:aeb1df146756	1161	(+) Requests can continue to be generated (feature ENABLED).
