Section Functional Description
2016 used with either system logic 2086/2087/2089 super chip. 2016 based condition /ROMCS signal determine which system logic work with. During power /ROMCS pulled high, works with system logic. /ROMCS pulled low, works with 2086/2087/2089 super chip. /RTCDS signal (pin requires pull through damping register system logic applications.
