Rev. A and B
• First Analog Comparator conversion may be delayed
• Asynchronous Oscillator does not stop in Power-down
1. First Analog Comparator conversion may be delayed
If the device is powered by a slow rising V
CC
, the first Analog Comparator conver-
sion will take longer than expected on some devices.
Problem Fix/Workaround
When the device has been powered or reset, disable then enable the Analog Com-
parator before the first conversion.
2. Asynchronous Oscillator does not stop in Power-down
The asynchronous oscillator does not stop when entering Power-down mode. This
leads to higher power consumption than expected.
Problem Fix/Workaround
Manually disable the asynchronous timer before entering Power-down.
