4.11.3.2
Static latch-up (LU)
Two complementary static tests are required on six parts to assess the latch-up performance:
A supply over-voltage is applied to each power supply pin.
A current injection is applied to each input, output and configurable I/O pin.
These tests are compliant with the EIA/JESD 78 IC latch-up standard.

Fast external crystal oscillator (4–40 MHz) electrical
characteristics
The device provides an oscillator/resonator driver. Figure 10 describes a simple model of the internal oscillator driver and
provides an example of a connection for an oscillator or a resonator.
Table 34 provides the parameter description of 4 MHz to 40 MHz crystals used for the design simulations.
