Figure 3−2 shows a 3-state bidirectional buffer. Section 14.2, Recommended Operating Conditions , provides the electrical characteristics of the inputs and outputs.
3−3 3.4.2 Device Resets The following are the requirements for proper reset of the PCI7x21/PCI7x1 1 controller: 1. GRST and PRST must both be asserted at power on. 2. GRST must be asserted for at least 2 ms at power on 3. PRST must be deasserted either at the same time or after GRST is asserted 4.
3−4 as bus master , by reading and writing PCI configuration registers . Setting bit 3 (SBDETECT) in the serial bus control/status register (PCI offset B3h, see Section 4.50) causes the PCI7x21/PCI7x1 1 controller to route the SDA an d SCL signals to the SDA and SCL terminals, respectively .
3−5 3.4.5 Function 2 (OHCI 1394) Subsystem Identification The subsystem identification register is used for system and option card identification purposes. This register can be initialized from the serial EEPROM or programmed via the subsystem access register at offset F8h in the PCI configuration space (see Section 7.
