Notes:
1. In SLEEP mode, the internal oscillator and reference current for LED drivers are off.
2. Average peak pixel current is measured at the maximum drive current set by Control Register 0. Individual pixels may exceed this value.

Notes:
1. Refers to the initial case temperature of the device immediately prior to measurement.
2. For comparison purpose with existing HCMS-29xx 5 V devices. The Typical and Minimum Luminous Intensity per LED Character Average can be
calculated by dividing the values in the table by two for the test condition 50% Peak Current, 100% Pulse Width and V_LED = 3.3 V.
3. Measured with all LEDs illuminated in a digit.
4. Dominant wavelength, λ_d, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the perceived
LED color.
