1 Pull-ups are generally only enabled on pins with their primary function, except as noted.
2 Refers to pin’s primary function.
3 Enabled only in oscillator bypass mode (internal crystal oscillator is disabled).
4 Serial boot must select 0-bit boot port size to enable the GPIO mode on these pins.
5 When the PCI is enabled, all PCI bus pins come up configured as such. This includes the PCI_GNT and PCI_REQ lines, which have
GPIO. The IRQ1/PCI_INTA signal is a special case. It comes up as PCI_INTA when booting as a PCI agent and as GPIO when booting
as a PCI host.
For the 360 TEPBGA, booting with PCI disabled results in all dedicated PCI pins being safe-stated. The PCI_GNT and PCI_REQ lines
and IRQ1/PCI_INTA come up as GPIO.
6 GPIO functionality is determined by the edge port module. The pin multiplexing and control module is only responsible for assigning
the alternate functions.
7 Depends on programmed polarity of the USB_VBUS_OC signal.
8 Pull-up when the serial boot facility (SBF) controls the pin
9 If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The pin multiplexing and control module is not
responsible for assigning these pins.
