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.
