I/O Registers
ADC Status and
Control Register
122
The following registers control and monitor operation of the ADC:
The ADC status and control register (ADSCR) contains a conversion
complete flag and four writable control bits. Writing to ADSCR clears the
conversion complete flag and starts a new conversion sequence.
CCF — Conversion Complete Flag

This read-only bit is automatically set when an analog-to-digital
conversion is complete, and a new result can be read from the ADC
data register. Clear the CCF bit by writing to the ADC status and
control register or by reading the ADC data register. Resets clear the
CCF bit.
