Product data sheet
8.7 Clock divider
8.8 Power-down and Idle mode
criteria, the boundary limits will again be compared after all 8 MSBs have been converted.
A boundary status register (BNDSTA0) flags the channels which caused a boundary
interrupt.
The A/D converter requires that its internal clock source be in the range of 500 kHz to
3 MHz to maintain accuracy. A programmable clock divider that divides the clock
from 1 to 8 is provided for this purpose.
In Idle mode the A/D converter, if enabled, will continue to function and can cause the
device to exit Idle mode when the conversion is completed if the A/D interrupt is enabled.
In Power-down mode or Total Power-down mode, the A/D does not function. If the A/D is
enabled, it will consume power. Power can be reduced by disabling the A/D.
