description

The TL16PNP100A responds to the plug-and-play (PnP) autoconfiguration process. The process puts all PnP cards in a configuration mode, isolates one PnP card at a time, assigns a card-select number (CSN), and reads the card resource-data structure from the ST93C56/66 EEPROM. After the resource requirements and capabilities are determined for all cards, the process uses the CSN to configure the card by writing to the configuration registers. The TL16PNP100A implements configuration registers only for I/O applications with two logical devices, and DMA application support is not provided. Finally, the process activates the TL16PNP100A card and removes it from configuration mode. After the configuration process, the logic function can then start responding to industry standard architecture (ISA) bus cycles. The controller disables the EEPROM interface after the configuration is complete to allow another on-board controller to access the EEPROM.
