Power Consumption
This section details the device power measurements taken over various operating conditions. Unless otherwise noted,
all measurements were taken with power supplies at nominal values (VDDIO, VDD1A, VDD2A = 3.3 V, VDDCR = 1.2 V).
See Section 3.8.3, "Power-Down Modes" for a description of the power down modes.
