In the following flow chart is detailed the proper restart procedure:

In order to prevent a back powering effect it is recommended to avoid

having any HIGH logic level signal applied to the digital pins of the

NE866B1 when the module is powered OFF or during an ON/OFF

transition.

Using bidirectional level translators which do not support High Z

mode during power off is not recommended.
