MPC5676R DMA interrupts

Question asked by Nick LaBianco on Jan 22, 2016

If I want to initiate DMA transfers using an external pin of the processor, which pins can I use? I found that there are 4 possible signals that can be used for this per reference manual pg. 3-15: IRQ[0], IRQ[1], IRQ[2], IRQ[3]. I found that these interrupts may be utilized on multiple uC pins as seen below. Am I able to use any of the pins below or only specific ones? How can I tell?
