The absolute parameter is tested when VBAT has the power but the PWRKEY has no pulled down.
If it is over the range, the module will be damage. If the power supply on VBAT pin had been shut
down, and the other pin should not have the voltage. Otherwise, it may lead to abnormally boot up
or damage the module.
