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
Thomas Harte	553f3b6d8b	Properly conforms to GPIP input/output blending.	2019-10-28 22:37:11 -04:00

Thomas Harte	22754683f8	Ensures timer divisor values don't go out of range, adds timer interrupts. ... I suspect further timer issues remain.	2019-10-26 23:20:13 -04:00
