Tail end of standard CIA-triggered interrupt, followed by start of another routine
|
|
|
|
LDA $DC0D is the standard way to clear interrupt status on the 6526 CIA.
|
|
Then we have the standard return from interrupt sequence for a 6502
|
|
(see the wikipedia page on 6502 interrupts, for example), followed by
|
|
loading A with $00 at the start of a following routine -- which is a not
|
|
uncommon way for routines to start.
|
|
|
|
In short, nothing creative nor copyrightable.
