CR2
OL0 Blink Enable
If a logical 1, this bit forces the OL0 {A
E} inputs to toggle between a
logical 0 and the input value at the selected blink rate prior to palette
selection. A value of the logical 0 does not affect the value of the OL0
{A
E} inputs. In order for overlay 0 bit plane to blink, bit CR0 must be set
to a logical 1.
CR1
OL1 Display Enable
If a logical 0, this bit forces the OL1 {A
E} inputs to a logical 0 prior to
selecting the palettes. A value of a logical 1 does not affect the value of
the OL1 {A
E} inputs.
