**Spelling errors/mistyped words
Yes, I know there are spelling errors, and things are mistyped. It
seems no matter how hard I try my fingers hit 't' twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times. I don't have the time or the will to check the spelling of
everything. Basic spell checking has been peformed. Please let me know
if there is anything that would lead to incorrect information, or
something is so mangled that it needs revising. But if you can
basically understand what was intended, just cope with it. Just
cope:-)
BTW, "110" port is an "I/O" port that has been OCRed badly, as is an
"1/0" port.

**HT22 386SX/286 Single Chip (25 MHz) c:Sep91
***Info:
The HT22 is an advanced PC/AT compatible, single-chip 80386SX/80286
system design solution. This highly integrated single chip allows
simple, low cost system design options while featuring high perfor-
mance, low power consumption, and minimum board space require-
ments. Advanced memory management features include support for page
mode, 2 or 4-way interleaving in both pipelined and non-pipelined
modes. The EMS 4.0 hardware implementation features dual sets of 32
registers with full context support for highest performance
optimization of extended local memory accesses. An advanced EMS
hardware write-protect option has been added for maximum EMS 4.0
compatibility. The HTZ2 supports 256K, 1M and 4MB DRAMs in 1 by 1 and
1 by 4 device configurations for up to 20MB of on-board system memory.
16MB is addressed directly by system resources, the remainder
addressed by the EMS mode.
A flexible Shadow RAM option for System and Video BIOS as well as 8-
16-bit BIOS options adds to overall design versatility.
A complete PC/AT compatible system with advanced features may be
implemented with minimal external support logic. The HT22 performs all
CPU and peripheral support functions in a single chip. Integrated
device functions include DMA Controllers, a Memory Mapper, Timers,
Counters, Interrupt Controllers, a Bus Controller and all supporting
circuitry for PC core logic requirements. The chip also contains all
the necessary address buffers, data transceivers, memory drivers,
parity checking and supporting circuitry for a complete high
performance computer solution. An asynchronous AT Bus clock allows
for a constant 8MHz Bus clock rate for highest bus device compat-
ibility as defined in IEEE Spec P996. This device is packaged in a
208-pin Plastic Quad Flat Pack.
