Note:
The "n" as the first letter of a signal name or the “#” as the suffix of a signal name indicates an "Active Low"
signal.
Note 1:
Buffer types per function on multiplexed pins are separated by a slash “/”. Buffer types in parenthesis
represent multiple buffer types for a single pin function.
Note 2:
The LPCPD# pin may be tied high. The LPC interface will function properly if the PCI_RESET# signal
follows the protocol defined for the LRESET# signal in the “Low Pin Count Interface Specification”.
Note 3:
For USB Hub functionality, the 32 KHz input clock must always be connected. There is a bit in the
configuration register at 0xF0 in Logical Device A that indicates whether or not the 32KHz clock is
connected. This bit determines the clock source for the fan tachometer, LED and “wake on specific key”
logic. This bit must always be set to ‘0’ (‘0’=32 KHz clock connected; reset default=‘0’).
Note 4:
The fan control pins (FAN1 and FAN2) come up as outputs and low following a VCC POR and Hard Reset.
These pins revert to their non-inverting GPIO
input
function when VCC is removed from the part.
Note 5:
The IRTX pins (IRTX2/GP35 and GP53/TXD2 (IRTX)) are driven low when the part is powered by VTR
(VCC=0V with VTR=3.3V). These pins will remain low following a power-up (VCC POR) until serial port 2
is enabled by setting the activate bit, at which time the pin will reflect the state of the transmit output of the
Serial Port 2 block.
Note 6:
The VCC power-up default for this pin is Logic “0” if the IRTX function is programmed on the GPIO.
Note 7:
VTR must not be connected to VCC. The 32 KHz input clock must not be driven high whenVTR = 0v.
