Where the times are defined as follows:
The VIO has been derived from a 2.75 V regulator. It is possible to
use this output as a power supply at 2.75 V with a maximum of 75mA.
It will indicate that the module is alive and it could power external
devices. In this case, the external applications do not need to
implement a 2.75 volt regulator to adapt the incoming (from module
point of view) serial data.
