Sets the step size of the spread spectrum. If set to zero or one, the value added to the FINE bits will be
incremented/decremented with one on every positive edge of the input clock. If set to n, the value added to the FINE bits will be
incremented/decremented with n on every positive edge of the input clock.
Sets the amplitude of the spread spectrum. If set to zero, only the LSB of the FINE bits will be affected. If set to one, the
sequence {1, 0, -1, 0} will be added to FINE bits, etc.
0: Each spread spectrum frequency is applied at constant intervals
1: Each spread spectrum frequency is applied at pseudo-random intervals
0: SSG is disabled.
1: SSG is enabled.
