The clock gate and reset control are still sep= arate, > are they not? On the A31 the "regular" port controler handles PA to PH banks, while the R_PIO handles the PL and PM banks. On the A23, the regular port controler handles PA to PL banks, and the R_PIO and PM bank doesn't exist. So we're not quite in the same situation. The A31 is troublesome, while the A23 (except for the external interrupts), is pretty much what we've seen so far with the A10/A20/...
