Abstract: A device includes a PWM circuit to generate a complementary PWM signal comprised of a positive polarity PWM signal and a negative polarity PWM signal. The positive polarity signal may drive a high-side switch. A trigger multiplexer may take as input the negative polarity PWM signal and may force an output based on a predetermined condition, the predetermined condition including but not limited to the maximum on-time of a low-side switch. The output of the trigger multiplexer may drive a low-side switch. The high-side switch and the low-side switch may drive a load.

Abstract: A microcontroller may include a DMA controller, a pattern matching circuit and a memory. The DMA controller may read a first descriptor word in the memory at a location addressed by a first descriptor pointer, and may move an input word from a location in the memory addressed by a source payload pointer to a location in the memory addressed by a destination payload pointer. The pattern matching circuit may perform a pattern matching operation based on the input word and one or more register values. The first descriptor pointer may be modified based on the results of the pattern matching circuit and may generate a second descriptor pointer value.
