7 / 23 page TL16PNP200 STANDALONE PLUGANDPLAY (PnP) CONTROLLER SLLS229A − NOVEMBER 1995 − REVISED APRIL 1996 7 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 default format On power up or reset, the TL16PNP200 starts generating read operations to the EEPROM. Each read transaction consists of read opcode, address, and data cycles (see EEPROM section). The data cycle is comprised to 16-bits. EEPROM addresses 0x00 through 0x0D store the power-up defaults. These defaults include the PnP configuration register defaults, I/O block size, DMA mapping, and OEN configuration. Table 1 is a description of the format for storing the defaults in the EEPROM. Table 1.
