1.4 SSC Modulation Profile

The modulation profile refers to the shape of the curve describing the variation of the modulated clock frequency. Conventional profiles include sinusoidal, triangular, sawtooth, and Hershey shape.

The AM62x, AM62Ax, AM62Px, and AM62Lx SoCs support triangular modulation by default. An external wave table can be used to modulate the clock frequency using a profile other than triangular.
