34 Electrical Characteristics
34.1 Absolute Maximum Ratings
Note that stresses beyond those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions beyond those indicated in the operational
sections of this specification are not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Notes: 1. Register VREG_CTRL needs to be programmed to disable internal voltage regulators and supply blocks by an external
1.8V supply, refer to section "Voltage Regulators (AVREG, DVREG)" on page 163 .

Note: 5. The capacitive load should not be larger than 50 pF for all I/Os when using the default driver strength settings, refer to
section "DPDS0 – Port Driver Strength Register 0" on page 174 and "DPDS1 – Port Driver Strength Register 1" on
page 175 . Generally, large load capacitances increase the overall current consumption.
