Notes:
* If not used as PCM, it can be used as a secondary UART for debugging. We strongly recommend that
the user has a 3-pin connector or 3 test points on their board, so that one can easily monitor and diagnose
their module.
** If the user wants the module to monitor battery voltage and the user is using a regulator in conjunction
with a battery, whose maximum voltage exceeds 4.3 V, to drive the module, then the user should please
contact our engineers.

When using a battery in which the voltage is between 3.3 V to 4.3 V and regulators aren’t used to drive
the module, leave this pin open.
