7497422667 Changed several things.
Removed the need to use async flip flops in SDC.
Added arrs, a synchronizer for reset.
I think this works with the real FPGA hardware.
The last build did not include this arrs but it worked.

69674f272a We now have a rough sdc read routine. 2021-09-25 17:51:38 -05:00

44196af61a Have program which checks for sdc init and issues read, but read done is
not correctly being read back by the software.  The error is in how the
sdc indicates busy.
