- cpu synchronization
|
||||||
|
|
||||||
|
SC1 and SC0 are used to provide CDP1864C-to-CPU synchronization for a jitter-free display.
|
||||||
|
During every horizontal sync the CDP1864C samples SC0 and SC1 for SC0 = 1 and SC1 = 0
|
||||||
|
(CDP1800 execute state). Detection of a fetch cycle causes the CDP1864C to skip cycles to
|
||||||
|
attain synchronization. (i.e. picture moves 8 pixels to the right)
