**ACC2016    Buffer and MUX Logic                                  c96
***Info:
The ACC Micro  2016 is designed to work together  with the system core
logic products to  provide the decoding logic for  the Real Time Clock
(RTC), address buffer,  and data buffer for the  486/386DX and Pentium
applications. At least seven TTLs can be saved when using the 2016.

The  2016  can  be  used  with  either  the  2268/2178/2168/2056/2057/
2066/2048 system logic  or the 2086/2087/2089 super chip.  The 2016 is
based on the condition of  the /ROMCS signal to determine which system
logic to work with.  During power up, if the /ROMCS is pulled high, it
works  with the  2268/2178/2168/2056/2057/2066/2048  system logic.  If
/ROMCS is pulled low, it works with the 2086/2087/2089 super chip. The
/RTCDS signal (pin 97) requires  a pull low through a damping register
for all system logic applications.
