This bit can be used to generate an EC interrupt.
0: ADC single-sample conversion is not complete. This bit is
cleared whenever an ADC conversion cycle begins for a single
conversion cycle.
1: ADC single-sample conversion is completed. This bit is set to 1
when all enabled channels in the single conversion cycle.
6 Repeat_Done_Status
This bit is cleared when it is written with a 1. Writing a 0 to this bit
has no effect.
This bit can be used to generate an EC interrupt.
0: ADC repeat-sample conversion is not complete. This bit is
cleared whenever an ADC conversion cycle begins for a repeating
