Important Note: If the V
is selected as a reset source. Selecting the V
lized may cause a system reset. In some applications, this reset may be undesirable. If this is not desirable
in the application, a delay should be introduced between enabling the monitor and selecting it as a reset
source. The procedure for enabling the V
state is as follows:
1. Enable the V
2. If necessary, wait for the V
3. Select the V

this is the case and the V
