32.3.1 ADC status and control registers 1 (ADCx_SC1n)
The SC1A register is used for both software and hardware trigger modes of operation.
To allow sequential conversions of the ADC to be triggered by internal peripherals, the
ADC can have more then one status and control register: one for each conversion. The
SC1B-SC1n registers indicate potentially multiple SC1 registers for use only in hardware
trigger mode. Refer to the Chip Configuration information about the number of SC1n
registers specific to this device. The SC1n registers have identical fields, and are used in
a "ping-pong" approach to control ADC operation.
At any one point in time, only one of the SC1n registers is actively controlling ADC
conversions. Updating SC1A while SC1n is actively controlling a conversion is allowed
(and vice-versa for any of the SC1n registers specific to this MCU).
