A/D Status and Control Register
A write to the A/D Status and Control register will cause the converter to abort the current
conversion; reset the COCO ag and start a new conversion on the selected channel.
COCO - Conversion Complete
1 (set)
Conversion is complete; a new result can be read from the A/D Data
register at address $28. The converter immediately starts a new
conversion. This bit is cleared by reading the A/D Data register,
writing to the A/D Status and Control register, power-on reset, or by
an external reset.
0 (clear) –
No conversion since last reset.
ADRC - A/D RC Oscillator Control
1 (set)
A/D uses RC clock.
0 (clear) –
A/D uses CPU clock
