monitor is enabled after power-on resets. Its defined state (enabled/disabled) is not altered by any other
reset source. For example, if the V

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 shown below:
1. Enable the V
