Note 2: A soft turn-on is produced by slewing up ø, from minimum to memory.

Upon power-up the memory value is defaulted to maximum conduction angle.

Note 3: “Memory” refers to the conduction angle, ø, which existed prior to the current off-state.

Note 5: NO = Dimming direction does not reverse from prior dimming direction.

YES = Dimming direction does reverse from prior dimming direction. N/A = Does not apply.
