Thomas Harte	4857ceb3eb	Attempts to get a bit more systematic. ... Spotted that interrupt_enable_ isn't being used properly while doing so, hopefully that's now correct.	2019-10-29 23:16:08 -04:00
Thomas Harte	1c154131f9	Expands size of storage in Cycles/HalfCycles; adjusts widely to compensate.	2019-10-29 22:36:29 -04:00
Thomas Harte	fd02b6fc18	Corrects in-service test; adds pending clearing upon enabled clearing.	2019-10-28 22:51:00 -04:00
