8.2 DC CHARACTERISTICS OF PINS, BY I/O BUFFER TYPES
The following tables summarize the DC characteristics of all device pins described in the Chapter 1.2 on page 9. The char-
acteristics describe the general I/O buffer types defined in Table 1. For exceptions, refer to Section 8.2.8. The DC charac-
teristics of the system interface meet the PCI2.2 3.3V DC signaling.
