I'm using TIM6-DAC-DMAMUX-DMA to create a periodic signal as shown in the following picture. The yellow curve is DAC output, and green curve is a toggled GPIO for debug. I catched an unexpected interrption time point which is described as followed:

Registers Setting: DMA_S0CR: MSIZE=PSIZE=16bit, DBM=1, MINC=1, CIRC=1, DIR=M2P, TCIE=1, EN=1DMA_S0NDTR = 8DMA_S0M0AR points to a buffer: 0x8000, 0x6000, 0x4000, 0x2000, 0x0000, 0x2000, 0x4000, 0x6000DMA_S0M1AR points to a buffer: 0x7000, 0x5000, 0x30...
