NOTES: 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 operating supply voltage is defined according to the trip point where POR is going active by decreasing supply voltage.
POR is going inactive when the supply voltage is raised above minimum supply voltage plus the hysteresis of the SVS circuitry.
3. The MSP430 CPU is clocked directly with MCLK.
Both the high and low phase of MCLK must not exceed the pulse width of the specified maximum frequency.
4. Modules might have a different maximum input clock specification. Refer to the specification of the respective module in this data
sheet.
