Just one important point to clarify over here, do we : 1) first check PrAcc in CONTROL reg *before* initiating FASTDATA acc (like I implemented), or do we 2) try FASTDATA transfer without first checking PrAcc in CONTROL reg, then check shifted-ot SPrAcc, and then in the end check PrAcc in CONTROL, like you suggested ? Basically, do we check PrAcc in CONTROL reg before or after FASTDATA transaction ?
