7.1.1.2.1
Air Discharge
To perform this test, a charged electrode is moved close to the system being tested until a spark is generated. This test
is difficult to reproduce because the discharge is influenced by such factors as humidity, the speed of approach of the
electrode, and construction of the test equipment.
7.1.1.2.2
Contact Discharge
The uncharged electrode first contacts the pin to prepare this test, and then the probe tip is energized. This yields more
repeatable results, and is the preferred test method. The independent test laboratories contracted by Microchip provide
test results for both types of discharge methods.

Note: The current at VDD_CORE is either supplied by the internal regulator from current entering at VDD33, or
from an external 1.8V supply when the internal regulator is disabled.
Note 7-1 This is calculated with full flexPWR features activated: VDDIO = 1.8V and internal regulator disabled.
