Tim Allen 5df775bbb0 Make the emulated 6551's soft ("program") reset state match the MOS datasheet. ... The only description of the effects of "program reset" in the original MOS datasheet is in the section for each register. The W65C51S and W65C51N datasheets have a heading "PROGRAM RESET OPERATION", but it amounts to: - internal registers are modified as described in the section for each register - changes to the DTR, DCD, and DSR pins which Symon does not emulate - the overrun flag is cleared ...which is what this new implementation does. It would make *sense* for the reset to do things like "cancel transmission or reception in progress" and stop asserting an interrupt, as the old code did, but I can't find any evidence of such behaviour in the datasheets.		2023-06-11 08:21:37 -07:00
