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

, 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.
