NOTES: 1. Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Since the PCB adds additional capacitance it is recommended to verify the correct load by measuring the ACLK frequency. For a
correct setup the effective load capacitance should always match the specification of the used crystal.
2. Requires external capacitors at both terminals. Values are specified by crystal manufacturers.

NOTE 1: This parameter defines the minimum supply voltage when the data in program memory RAM remain unchanged. No program execution
should take place during this supply voltage condition.
