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.
