Short Read Only must be disabled in the IDMA Overlay memory mapped register.
Consider using the Short Read Only mode, instead, because Short Read mode is not applicable at high clock frequencies.
Start of Read = IS Low and IRD Low.
DM Read or first half of PM Read.
Second half of PM Read.
End of Read = IS High or IRD High.
