***Info:
GENERAL DESCRIPTION

The W83977TF  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  plug-andplay
registers for  the whole chip  --- plus additional  powerful features:
ACPI,  8042 keyboard controller  with PS/2  mouse support,  23 general
purpose  I/O  ports,  full  16-bit address  decoding,  OnNow  keyboard
wake-up, OnNow mouse wake-up.

The disk  drive adapter  functions of W83977TF  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 into
the  W83977TF greatly reduces  the number  of components  required for
interfacing with floppy disk  drives. The W83977TF 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  W83977TF  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   W83977TF  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 95TM, which makes system resource allocation
more efficient than ever.

W83977TF   provides  functions   that  comply   with   ACPI  (Advanced
Configuration and  Power Interface), which includes  support of legacy
and ACPI power management through  SMI or SCI function pins.  W83977TF
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 is available with  optional AMIKEY-2, Phoenix MultiKey/42, or
customer code.

The W83977TF 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.

W83977TF is made  to fully comply with Microsoft  PC97 Hardware Design
Guide. IRQs,  DMAs, and I/O space  resource are flexible  to adjust to
meet  ISA PnP  requirement.  Moreover  W83977TF is  made  to meet  the
specification of PC97's requirement  in the power management: ACPI and
DPM (Device Power Management).

Another  benifit is  that  W83977TF  has the  same  pin assignment  as
W83977AF, W83977F, W83977ATF.  This makes the design very flexible.
