13. Parallel Port Description
SB16C1053APCI offers one Parallel Port supporting Compatibility/Nibble/Byte/EPP/ECP modes. The Parallel
Port complies with IEEE standard 1284. And it is host-based multi-function parallel port that be to transfer data
between a host PC and a peripheral such as printers, scanners and external drives. The register set of the
Parallel Port is compatible with Microsoft register definition.
When SB16C1053APCI is set to 1P or 2S1P mode, the Parallel Port would be activated. BAR2 of PCI
Configuration Space is assigned to basic registers of Parallel Port. And BAR3 of PCI Configuration Space is
assigned to extended registers of ECP mode.
Two Base Address Range, BAR2 and BAR3 are re-locatable.
When the user this parallel port in DOS mode, please set the BAR2 and BAR3 to DOS LPT1 ~ LTP3 ranges.
