Description
Infrared Data Transmit. Infrared Data Transmit.
Infrared Data Receive. Infrared Data Receive Low.
24 MHz or 48 MHz Clock Input.
General Purpose I/O 10
General Purpose I/O 17 - 14
Case Open Detection #. The Case Open input is connected to a
low power CMOS Flip-Flop, which is especially designed to support
the case open state by the battery during power loss state.
Power On Switch Output #/ Power Management Event #.
• The first function of this pin is the Main power On-Off switch Output
# (Bug fix for PIIX40).
• The second function of this pin is the power management event #.
It supports the PCI PME# interface. This signal allows the
peripheral to request the system to wake up from D3 (cold) state.
This pin is backed by VTR.
• The function configuration of this pin is decided by the software
configuration registers.
Panel Switch Input #. Main power On-Off switch Input. (Bug fix for
PIIX4 )
Power Supply On Output / General Purpose I/O 11.
• The default function of this pin is Main power supply On Output.
( Bug fix for PIIX4 )
• The second function of this pin is the GP11.
• The function configuration of this pin is decided by the GPIO
configuration registers.
• No Connection.
