(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) All voltages referenced to V_SS. VCORE is for internal device use only. No external dc loading or voltage should be applied.
(3) Higher temperature may be applied during board soldering according to the current JEDEC J-STD-020 specification with peak reflow
temperatures not higher than classified on the device label on the shipping boxes or reels.

(1) It is recommended to power AV_CC and DV_CC from the same source. A maximum difference of 0.3 V between AV_CC and DV_CC can be
tolerated during power up and operation.
(2) The minimum supply voltage is defined by the supervisor SVS levels when it is enabled. See the PMM, SVS High Side threshold
parameters for the exact values and further details.
(3) The MSP430 CPU is clocked directly with MCLK. Both the high and low phase of MCLK must not exceed the pulse duration of the
specified maximum frequency.
(4) Modules may have a different maximum input clock specification. See the specification of the respective module in this data sheet.
