The FDC37M60x incorporates an IBM XT/AT
compatible parallel port.
optional PS/2 type bi-directional parallel port
(SPP), the Enhanced Parallel Port (EPP) and
the Extended Capabilities Port (ECP) parallel
port modes.
Registers for information on disabling, power
down, changing the base address of the parallel
port, and selecting the mode of operation.

STATUS PORT
CONTROL PORT
EPP ADDR PORT
The bit map of these registers is:
Note 1: These registers are available in all modes.
Note 2: These registers are only available in EPP mode.
Note 3 : For EPP mode, IOCHRDY must be connected to the ISA bus.

The parallel port 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:
