478  * This operation triggers the conversion when in software trigger mode. When in hardware trigger mode, this API
479  * configures the channel while the external trigger source helps to trigger the conversion.
480  *
481  * Note that the "Channel Group" has a detailed description.
482  * To allow sequential conversions of the ADC to be triggered by internal peripherals, the ADC has more than one
483  * group of status and control registers, one for each conversion. The channel group parameter indicates which group of
484  * registers are used, for example, channel group 0 is for Group A registers and channel group 1 is for Group B
485  * registers. The
486  * channel groups are used in a "ping-pong" approach to control the ADC operation.  At any point, only one of
487  * the channel groups is actively controlling ADC conversions. The channel group 0 is used for both software and
488  * hardware
489  * trigger modes. Channel group 1 and greater indicates multiple channel group registers for
490  * use only in hardware trigger mode. See the chip configuration information in the appropriate MCU reference manual for
491  * the
492  * number of SC1n registers (channel groups) specific to this device.  Channel group 1 or greater are not used
493  * for software trigger operation. Therefore, writing to these channel groups does not initiate a new conversion.
494  * Updating the channel group 0 while a different channel group is actively controlling a conversion is allowed and
495  * vice versa. Writing any of the channel group registers while that specific channel group is actively controlling a
496  * conversion aborts the current conversion.
