**W83757 SUPER I/O CHIP <92
***Info:
GENERAL DESCRIPTION
The W83757 is a super multi I/O chip that combines the functions of a
Floppy Disk Drive adapter, serial (UART)/parallel adapter, IDE bus and
game port. The W83757's disk drive adapter functions include a
standard Floppy Disk Drive controller, data separator, write
precompensation circuit, decode logic, data rate selection, clock
generator, drive interface control logic, interrupt and DMA logic,
thus greatly reducing the number of components required to interface
floppy disk drives. As a UART, the chip supports serial to parallel
conversion on data characters received from a peripheral device or a
MODEM, and parallel to serial conversion on data characters received
from the CPU. The CPU can read the complete status of the UART at any
time during operation. The UART includes a programmable baud rate
generator, complete MODEM control capability and a processor-interrupt
system. As a parallel port, the W83757 provides the user with a fully
bidirectional parallel centronics-type printer interface. Besides the
above functions, this chip also supports two Embedded Hard Disk Drives
(AT bus interface) and a game port decoder.
