Raster operation interrupt
is
1Jsed
to make sure an
interrupt
is
generated properly after raster operation is completed.
The raster operation interrupt count is used to keep track of the
number of interrupts generated during two raster operations.
V-sync interrupt
is
used to make sure
a
vertical
s~,-nchronizat
ion
interrupt
is
generated properly.
The V-sync interrupt count is used to keep track of the number of
V-sync
interrupts generated during one second
(created
using
a
program Loop).
It
checks W'hether the number of
interrupts
is
bO
(approximately) as
it
should be.
