1 / 21 page TL16PNP100A STANDALONE PLUG-AND-PLAY (PnP) CONTROLLER SLLS200C – MARCH 1995 – REVISED SEPTEMBER 1997 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D PnP Card Autoconfiguration Sequence Compliant D Supports Two Logical Devices D Decodes 10-Bit I/O Address Location With Programmable 1-, 2-, 4-, 8-, 16-Byte Block Size D Maps Interrupts to Six Interrupt Outputs IRQ3 – IRQ7 and IRQ9 D Provides Simple 3-Terminal Interface to SGS-Thomson EEPROM 2K/4K ST93C56/66 or Equivalent D 3-State Output EEPROM Interface Allows the EEPROM to be Accessed by Another Controller D Provides Direct Connection to ISA/AT Bus D Data and Interrupt Signals Require No Buffer D Available in 44-Pin Plastic Leaded Chip Carrier (PLCC) and 48-Pin TQFP Package 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 regis- ters 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.
