**W83777F/87F     Power I/O   (Multi I/O)                          <95
***Info:
GENERAL DESCRIPTION

The  W83777F/W83787F  integrates a  disk  drive  adapter, serial  port
(UART), parallel port, IDE bus interface, and game port decoder onto a
single I/O  chip. The  W83777F/W83787F is an  enhanced version  of the
W83767F  Power l/O  chip. The  enhanced functions  include  one 2.88MB
floppy disk controller (W83777F only), two 16550 compatible UARTs, and
one parallel port with EPP mode, ECP mode, and joystick mode.

The  disk drive  adapter functions  of the  W83777F/W83787F  include a
floppy  disk drive  controller compatible  with the  industry standard
82077/765,  data  separator,  write pre-compensation  circuit,  decode
logic, data  rate selection, clock generator,  drive interface control
logic,  and interrupt  and  DMA  logic. The  wide  range of  functions
integrated  onto the  W83777F/W83787F  greatly reduces  the number  of
components  required  for interfacing  with  floppy  disk drives.  The
W83777F/W83787F  supports  four  360K,  720K, 1.2M,  1.44M,  or  2.88M
(W83777F  only)  disk  drives  and  data transfer  rates  of  250KB/S,
300KB/S, 500KB/S, and 1MB/S (W83777F only).

There  are two high-speed  serial communication  ports (UARTs)  on the
W83777F/W83787F.  The  UARTs  include  16-byte send/receive  FIFOs,  a
programmable baud  rate generator, complete  modem control capability,
and a processor interrupt system.

The  W83777F/W83787F  supports  three optional  PC-compatible  printer
ports: 378b, 278h and  BBCh.  Additional bi-directional l/O capability
is available by hardware control or software programming. The parallel
port  also supports  the  Enhanced Parallel  Port  (EPP) and  Extended
Capabilities  Port (ECP).  The  W83777F/W83787F supports  two embedded
hard  disk drive  (AT bus)  interfaces and  a game  port  with decoded
read/write output.

The W83777F/W83787F's Extension FDD Mode and Extension 2FDD Mode allow
one or two external floppy disk drives to be connected to the computer
through the printer interface pins in notebook computer applications.

The  Extension  Adapter  Mode  of the  W83777F/W83787F  allows  pocket
devices to be installed through the printer interface pins in notebook
computer applications according to a protocol set by Winbond, but with
upgraded performance.

The JOYSTICK mode allows a joystick to be connected to a parallel port
with a signal switching cable.

The configuration register supports address selection, mode selection,
function enable/disable, and power down function selection.
