Thomas Harte
0245b040b0 Splits TOD storage by model. 
TOD storage will probably end up being a full-on class.

8795719c18 This counts reloads, most accurately. 2021-08-03 17:12:08 -04:00
Thomas Harte
6bbbf43341 At least attempts to chain correctly. 2021-08-03 17:03:58 -04:00
Thomas Harte
ee6039bfa5 Writes to a timer _during reload_ now have effect. 
Net: one CIA test passed.
 2021-08-03 16:57:05 -04:00

ef58ce6277 Gets a bit more rigorous about the clocking stage. 
Albeit without advancing relative to the test.
 2021-08-02 21:04:00 -04:00
Thomas Harte
15de5e98c4 Adds [partial] test for whether counters are linked. 2021-08-02 20:17:37 -04:00
Thomas Harte
38848ca2db Rationalises reload logic and cuts storage. 
Failure point is now chaining, I think.
 2021-08-02 20:14:01 -04:00
Thomas Harte
77c627e822 Ensure that reading the interrupt flags really clears the master bit. 
Also makes some guesses on one-shot and reload timing. Alas the test isn't in itself specific enough to be more systematic here.

37a55c3a77 Corrects 6526 interrupt control write. 
This seems to imply that the 6526 should be interrupting too.

bcb7bb5cce Improves logging further. 
To investigate the new perpetual loop.

Thomas Harte
fcd6b7b0ea Takes further aim at the conters. 
I think test cases are needed, probably.
