PARALLEL PORT
The FDC37C665IR incorporates one IBM XT/AT
compatible parallel port. The FDC37C665IR
supports the optional PS/2 type bi-directional
parallel port (SPP), the Enhanced Parallel Port
(EPP) and the Extended Capabilities Port (ECP)
parallel port modes. Refer to the FDC37C665IR
Configuration
Registers
information on disabling, power down, changing
the base address of the parallel port, and
selecting the mode of operation.
description
for
The FDC37C665IR also incorporates SMSC's
ChiProtect circuitry, which prevents possible
damage to the parallel port due to printer power-
up.
The functionality of the Parallel Port is achieved
through the use of eight addressable ports,
with their associated registers and control
gating. The control and data port are read/write
by the CPU, the status port is read/write in the
EPP mode. The address map of the Parallel
Port is shown below:
DATA PORT
STATUS PORT
CONTROL PORT
EPP ADDR PORT
The bit map of these registers is:

EPP DATA PORT 1
EPP DATA PORT 2
