Picture1 show the relationship which PIT you should use when configure the DMA channel in periodic triggering mode 

if i choose the DMA 16  channel , and choose the DMAMUX_1 source 3 , then which PIT channel i should configure as a periodic trigger?

DMAMUX_1.CHCFG[0].R = 0xC3;// enable periodic triggering mode  ,i think PIT channel 0 or 2?
