Notes:
1.
VOH spec does not apply to signals that are open drain driver. Open drain signals must have an
external pull up resistor.
49.5.10.3 GPIO AC Specifications
The AC electrical specifications of the GPIO interface are compliant with the PCI Local
Bus Specification, Rev. 3.0 (refer to the AC Specifications for 3.3V Signaling for more
information).

IICH Interrupt Signal
This section describes the electrical characteristics of the IICH interrupt signal
interface.
49.5.11.1 IICH Interrupt Signal List
For IICH interrupt signal pin descriptions, refer to Table 48-12, “IICH Interrupt Signals”
