30. This pin requires an external 4.7-kΩ pull-down resistor to prevent PHY from seeing a valid Transmit Enable before it is actively
33. PF[21:22] are multiplexed as cfg_dram_type[0:1]. THEY MUST BE VALID AT POWER-UP, EVEN BEFORE HRESET
35. When a PCI block is disabled, either the POR config pin that selects between internal and external arbiter must be pulled
36.MDIC[0] is grounded through an 18.2-Ω precision 1% resistor and MDIC[1] is connected to GV
39. If PCI is configured as PCI asynchronous mode, a valid clock must be provided on pin PCI_CLK . Otherwise the processor
41.These pins should be tied to SCOREGND through a 300 ohm resistor if the high speed interface is used.
43. It is highly recommended that unused SD_RX/SD_RX lanes should be powered down with lane_x_pd. Otherwise the

46. Must be high during HRESET. It is recommended to leave the pin open during HRESET since it has internal pullup resistor.
47. Must be pulled down with 4.7-kΩ resistor.
48. This pin must be left no connect.

down to select external arbiter if there is any other PCI device connected on the PCI bus, or leave the PCIn_AD pins as "No
Connect" or terminated through 2–10 KΩ pull-up resistors with the default of internal arbiter if the PCIn_AD pins are not
connected to any other PCI device. The PCI block will drive the PCIn_AD pins if it is configured to be the PCI arbiter—through
POR config pins—irrespective of whether it is disabled via the DEVDISR register or not. It may cause contention if there is any
other PCI device connected on the bus.
