5 / 23 page TL16PNP200 STANDALONE PLUGANDPLAY (PnP) CONTROLLER SLLS229A − NOVEMBER 1995 − REVISED APRIL 1996 5 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION PNP_BUSY 65 O Plug-and-play busy. PNP_BUSY signal requests access to the EEPROM and is asserted during PNP configuration. On-board logic uses this signal to determine when it can access the EEPROM. This signal can also be used as a soft reset. RESET 41 I Reset. When active (high), RESET clears most logical device registers and puts the TL16PNP200 in the wait-for-key state. All configuration registers are loaded with their power-up defaults, and card select number (CSN) is reset to 0. SCLK 63 O Serial clock (3-state output path). SCLK controls the serial bus timing for address and data. A 100 µA pulldown transistor is connected internally to this terminal. SCS 64 O EEPROM chip select. SCS controls the activity of the EEPROM. A 100 mA pulldown transistor is connected internally to this terminal. SIO 62 I/O Serial input/output. SIO is a 3-state bidirectional EEPROM I/O data path. A 100 µA pulldown transistor is connected internally to this terminal . SROM_BUSY 69 I Serial EEPROM busy. SROM_BUSY is asserted by on-board logic during its access to the EEPROM. VCC 10,32, 46,68 5-V supply voltage. detailed description modes of operation The TL16PNP200 operates in one of two modes: Mode 0 or Mode1. The mode is selected by setting the mode bit in the power-up defaults (see defaults format section). Mode 0: • Supports two logical devices • Supports memory, I/O, IRQ, and DMA for each of the two logical devices • Routes device DMA request to three DMA channels that can be connected to any three DMA channels on the ISA bus • Has one configurable OEN signal Mode 1: • Supports five logical devices • Supports I/O and IRQ for the five logical devices and supports DMA for two logical devices • Routes device DMA requests to five DMA channels that can be connected to any five DMA channels on the ISA bus • Has two configurable OEN signals |
