**UM82C210     386SX/286 AT Chip Set                               <91
***Info:
The  UM82C210 is  an enhanced  PC/AT compatible  chip set  which  is a
highly integrated VLSI implementation of the control logic used in the
IBM AT. Due to its flexible architecture, the UM82C210 can be used, in
any  80286 based  systems.  The  UM82C210 chip  set consists  of three
chips  which  are:  UM82C211  (System  Controller),  UM82C212  (Memory
Controller), and UM82C215 (Data /Address Buffer).

The UM82C211,  System controller, provides all control  signals for AT
bus   including  bus   synchronization.  In   order  to   meet  timing
requirements  for different peripheral  boards, the  UM82C211 provides
programmable command delays and wait states.

The  UM82C212, Memory  Controller, provides  both  conventional memory
access and Page  Interleaved memory access. The UM82C212  also has LIM
EMS features that  support up to 8 MB of  on-board DRAMs. In addition,
the Shadow  RAM feature of  the UM82C212 allows faster  execution BIOS
codes.

The  UM82C215, Data/Address  Buffer, provides  buffering  and latching
functions between address buses and  data buses. It also generates the
parity bit and detects parity errors.
