AM2732-Q1: EDMA2 and EDMA3

Part Number: AM2732-Q1


In the safety manual <SWRU569_AM273x_Safety_Manual_22_sep_revA.pdf>:


EDMA2 - Information redundancy techniques

EDMA3- Transmission Redundancy for DMA

Why we only choose EDMA3 for ASIL B design but not EDMA2, Why ? for EDMA3, do you think it is meaningful to transfer two times ?
