SMSC DS – SP37E760
Rev. 04/13/2001
5
The SP37E760 incorporates an IBM XT/AT compatible parallel port. The SP37E760 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 SP37E760 Configuration Registers and the following hardware configuration description for
information on disabling, powering down, changing the base address, and selecting the mode of operation of the
parallel port.
The SP37E760 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 and bit encoding of the Parallel Port registers is shown in Table 13; the Parallel Port
Connector is shown in Table 14.
