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
D0
capabilities are determined for all cards, the
D1
process uses the CSN to configure the card by
D2
writing to the configuration registers. The
D3
TL16PNP100A implements configuration regis-
GND
ters only for I/O applications with two logical
D4
devices, and DMA application support is not
NC
provided. Finally, the process activates the
D5
TL16PNP100A card and removes it from
D6
configuration mode. After the configuration
D7
process, the logic function can then start
GND
responding to industry standard architecture
(ISA) bus cycles. The controller disables the
IRQ3
EEPROM interface after the configuration is
complete to allow another on-board controller to
access the EEPROM.
