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. Measured with all LEDs illuminated in a digit.
3. Dominant wavelength, ld, is derived from the CIE Chromaticity diagram and represents the single wavelength which defines the perceived LED
color.
