T echnical Data
10.6.2 A/D Data Register
10.7 A/D During WAIT Mode
Technical Data
NOTE:
Channel 0 and 7–15 convert internal signals which cannot be accessed
externally.
One 8-bit result register is provided. This register is updated each time
COCO is set.
The A/D converter continues normal operation during WAIT mode. To
decrease power consumption during WAIT it is recommended that both
the ADON and ADRC bits in the A/D status and control registers be
cleared if the A/D converter is not being used. If the A/D converter is in
use and the system clock rate is above 1.0 MHz it is recommended that
the ADRC bit be cleared.
As the A/D converter continues to function normally in WAIT mode the
COCO bit is not cleared.
