**W83977EF        WINBOND I/O (Multi I/O)                          <98
***Info:
GENERAL DESCRIPTION

The W83977EF  is an evolving  product from Winbond's most  popular I/O
chip W83877F --- which integrates  the disk drive adapter, serial port
(UART),  IrDA  1.0  SIR,  parallel port,  configurable  plugand-  play
registers for  the whole chip  --- plus additional  powerful features:
ACPI,  8042 keyboard controller  with PS/2  mouse support,  14 general
purpose  I/O  ports,  full  16-bit address  decoding,  OnNow  keyboard
Wake-Up, OnNow mouse Wake-Up.

The disk  drive adapter  functions of W83977EF  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  W83977EF greatly reduces  the number  of components  required for
interfacing with floppy disk  drives. The W83977EF supports four 360K,
720K, 1.2M, 1.44M, or 2.88M disk drives and data transfer rates of 250
Kb/s, 300 Kb/s, 500 Kb/s,1 Mb/s, and 2 Mb/s.

The  W83977EF  provides  two  high-speed  serial  communication  ports
(UARTs),  one of  which supports  serial Infrared  communication. Each
UART includes  a 16-byte send/receive  FIFO, a programmable  baud rate
generator,  complete   modem  control  capability,   and  a  processor
interrupt system. Both UARTs provide legacy speed with baud rate up to
115.2k bps and  also advanced speed with baud rates  of 230k, 460k, or
921k bps which support higher speed modems.

The   W83977EF  supports   one  PC-compatible   printer   port  (SPP),
Bi-directional  Printer port  (BPP)  and also  Enhanced Parallel  Port
(EPP) and  Extended Capabilities Port (ECP). Through  the printer port
interface pins,  also available are: Extension FDD  Mode and Extension
2FDD  Mode allowing  one  or two  external  floppy disk  drives to  be
connected.

The   configuration  registers   support   mode  selection,   function
enable/disable, and  power down function  selection.  Furthermore, the
configurable  PnP  features  are  compatible  with  the  plug-and-play
feature demand  of Windows 95, which makes  system resource allocation
more efficient than ever.

W83977EF  provides   functions  that  complies   with  ACPI  (Advanced
Configuration and  Power Interface), which includes  support of legacy
and ACPI power  management through SMI or SCI  function pins. W83977EF
also  has auto  power  management to  reduce  power consumption.   The
keyboard controller is based on 8042 compatible instruction set with a
2K  Byte programmable  ROM  and  a 256-Byte  RAM  bank. Keyboard  BIOS
firmware are available with optional AMIKEY-2, Phoenix MultiKey/42, or
customer code.

The W83977EF provides  a set of flexible I/O  control functions to the
system designer through a set of General Purpose I/O ports. These GPIO
ports may  serve as  simple I/O or  may be individually  configured to
provide a predefined alternate function.

The W83977EF  also supports Power-loss  control, and makes  the system
never miss to detect any Wake-Up event provided by the chipset such as
INTEL PIIX4.

I/O  space   resource  are  flexible   to  adjust  to  meet   ISA  PnP
requirement. Moreover  W83977EF is made  to meet the  specification of
PC98's requirement in the power management: ACPI and DPM (Device Power
Management).

Another  benifit is that  W83977EF is  of the  same pin  assignment of
W83977AF,  W83977F, W83977TF,  W83977ATF. Thus  makes the  design very
flexible.
