2 / 98 page

General Description (Continued)

The parallel port is fully IEEE 1284 level 2 compatible The

SPP (Standard Parallel Port) is fully compatible with ISA

EISA and MicroChannel parallel ports In addition to the

SPP EPP (Enhanced Parallel Port) and ECP (Extended Ca-

pabilities Port) modes are supported by the parallel port

All IDE control signals are provided by the PC87332 Only

external signal buffers are required to implement a complete

IDE interface

A set of eight configuration registers are provided to control

various functions of the PC87332 These registers are ac-

cessed using two 8-bit wide index and data registers The

ISA IO address of the register pair can be relocated using a

power-up strapping option

When idle advanced power management features allows

the PC87332 to enter extremely low power modes under

hardware or software control The PC87332VLJ can oper-

ate from a 5V or a 33V power supply An unique IO cell

structure allows the PC87332VLJ to interface directly with

5V external components while operating from a 33V power

supply
