(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) CAUTION: ESD-sensitive device. Precautions should be used when handling the device in order to prevent permanent damage.

(1) The CC2538 contains a power on reset (POR) module and a brown out detector (BOD) that prevent the device from operating under
unsafe supply voltage conditions. In the two lowest power modes, PM2 and PM3, the POR is active but the BOD is powered down,
which gives a limited voltage supervision.
If the supply voltage is lowered to below 1.4 V during PM2/PM3, at temperatures of 70°C or higher, and then brought back up to good
operating voltage before active mode is re-entered, registers and RAM contents that are saved in PM2, PM3 may become altered.
Hence, care should be taken in the design of the system power supply to ensure that this does not occur. The voltage can be
periodically supervised accurately by entering active mode, as a BOD reset is triggered if the supply voltage is below approximately
1.7 V.
