Does the scanline counter (LY) keep counting when the display is disabled? Does it freeze at whatever it was before, keep counting, or go to zero? Does the LY==LYC check still happen while the display is disabled?

EDIT:
BGB emulates it like this: Sets LY to zero when turning off the display, LY doesn't count up at all, LY == LYC check does not happen.
