Started thinking about how to quickly read from HyperRam…
Think the best way is to have data on either P0..P7 or P32..P39.
This way, can do a REP loop with WFBYTE on INA (or INB) to transfer data at maximum rate.
If the P2 is at 250 MHz, then will clock HyperRam at 62.5 MHz.
Will use WAITSE1 to wait for HyperRam to raise RWDS, signaling that first byte is ready.
Then, start WFBYTE loop.
Maybe this is all wrong, but if it works, would have 125 MBPS read rate.
One thing I am aware of is that we can't cross a row boundary this way.
Think that means limited to read length max of 1024 bytes at a time...
