description
The TL16PNP200A is an Industry Standard Architecture (ISA) plug-and-play (PnP) controller that provides
autoconfiguration capability to ISA cards according to the ISA PnP 1.0 a specification. It interfaces to a serial
EEPROM, where card resource requirements and power-up defaults are stored. On power up, the controller
loads the default configuration from the EEPROM making it ready for operation (non-PnP systems) or to be
configured by the PnP configuration process (PnP-capable systems). During configuration mode, the PnP
autoconfiguration process reads the card resource requirements, configures the card by writing to the
TL16PNP200A configuration registers, activates the device, and removes it from the configuration mode.
Thereafter, the TL16PNP200A routes all ISA transactions between the card and the ISA bus. The
TL16PNP200A operates in one of two modes. In mode 0, the device supports two logical devices with memory,
I/O, interrupt, and DMA resources for each device. In mode 1, the device supports five logical devices with I/O
and interrupt resources for all logical devices and DMA resources for two of the five logical devices; there is no
memory support in mode 1. The TL16PNP200A provides interface signals to allow on-board logic access to the
serial EEPROM.
