c1bae49a92 Standardises on read and write for bus accesses. 
Logic being: name these things for the bus action they model, not the effect they have.

35fe4d50d4 Adds command termination upon drive becoming unready, and copies head and drive selection into ST0. 2017-09-15 20:26:41 -04:00
Thomas Harte
4d4a0cf1d2 Puts the disk controller back into the loop with knowledge about reading mode, and uses that knowledge to cut off the PLL. 2017-09-14 22:30:40 -04:00
Thomas Harte
b62f3e726a Adds a start-of-execution-phase get-out for drives that aren't ready. 2017-09-12 20:43:53 -04:00
Thomas Harte
d3c385b471 Separates the 8272's drive selection signalling from actual drive ownership. 
Thereby returns working motor control to the CPC.

96bf133924 Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed. 
In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

0622187ddf Strips Controller of all capabilities now housed on the Drive. 2017-09-10 19:23:23 -04:00
Thomas Harte
e88a51e75e Worked logic all the way down to the CPC. If the 8272 announces that it is asleep, it is now no longer clocked. Also very slightly cut down on IRQ line chatter to the Z80. 2017-08-20 12:05:00 -04:00
Thomas Harte
2d9efccc98 Introduced a master 'is sleeping' flag. I'm starting to think there's a pattern forming here. 2017-08-20 10:43:53 -04:00
Thomas Harte
8ce46b6e49 Having spotted that I was using my single-character loop counter names incorrectly (quelle surprise!), got a bit more explicit. Also flattened into a single loop so that I can break rather than returning. 2017-08-20 10:32:09 -04:00
Thomas Harte
669e0caff5 Ensured the head_unload_delay values are properly seeded, and generalised the quick escape. 2017-08-19 22:06:56 -04:00
Thomas Harte
aefbafa18d Centralised the 8272's actions of setting the non-DMA execution flag, picking the drive and head and loading the head for accessing commands, and switched error flag if read ID doesn't find anything. 2017-08-15 21:49:10 -04:00

d12c834f9c Increased amount reported. 2017-08-15 20:35:33 -04:00

709257a0c5 Quick fix: also treat reception of sync as a reason not to stop looking for a data address mark. 2017-08-15 20:16:56 -04:00
Thomas Harte
75a9d2bb33 Started withdrawing logging, reduced index hole count back to the correct number and tried to increase read_data rigour. 2017-08-15 20:12:01 -04:00
Thomas Harte
73080d6c36 Added an easy way for disk controllers to clamp termination of written data exactly to the index hole. 
This commit also temporarily provides a whole load of extra logging and minor logic improvements from the 8272. I'm mid-flow on finding a particularly vicious error in its handling of writing; wait for the pull request. But, at least: now waits for the first part of a post-ID gap before writing data, and attempts partially to handle appearance of the index hole during writing a track. More work to do on that though.

9d77f33611 Dealt with another source of repeating magic constants: the command numbers. 2017-08-15 11:06:10 -04:00
Thomas Harte
7d132f81f7 Increased logging by quite a distance and made an attempt once again to allow the processor some time to supply the first byte when writing before declaring overrun. 2017-08-15 10:50:28 -04:00
Thomas Harte
6553bf05b4 Corrected multi-sector reads: ensured the incremented sector number isn't replaced by the original, and that the controller returns to scanning mode. 2017-08-14 22:27:31 -04:00
Thomas Harte
0816d3f5a9 Corrected 'read deleted data' command. It's 0xc, not 0xb. 2017-08-14 21:41:20 -04:00
Thomas Harte
a366298022 Factored out the standard [M]FM gap and mark groups, to increase 8272 readability and because it's pretty-much certain I'll need them again if ever I try to tackle e.g. the 8271. 2017-08-14 16:03:35 -04:00
Thomas Harte
4df9307d25 Factored out the dull and repetitious stuff of writing n bytes of the same value. 2017-08-14 15:50:36 -04:00
Thomas Harte
9038ba622e Added a quick version of read track. 2017-08-14 14:34:56 -04:00

7b8bb0297a Implemented single density version of format track. 2017-08-14 13:03:17 -04:00
