10.This output is actively driven during reset rather than being three-stated during reset.
11.These JTAG pins have weak internal pull-up P-FETs that are always enabled.
12.These pins are connected to the V
13.Anode and cathode of internal thermal diode.
14.Treat pins AC7, T5, V2, and M7 as spare configuration pins cfg_spare[0:3]. The spare pins are unused POR config pins. It
15.If this pin is connected to a device that pulls down during reset, an external pull-up is required to drive this pin to a safe state
16.This pin is only an output in FIFO mode when used as Rx flow control.
17.Do not connect.
18.These are test signals for factory use only and must be pulled up (100 Ω to 1 kΩ) to OV
19.Independent supplies derived from board V
20.Recommend a pull-up resistor (1 K~) be placed on this pin to OV
21.The following pins must not be pulled down during power-on reset: HRESET_REQ, TRIG_OUT/READY/QUIESCE,
22.This pin requires an external 4.7-kΩ pull-down resistor to prevent PHY from seeing a valid transmit enable before it is actively
23.General-purpose POR configuration of user system.
24.When a PCI block is disabled, either the POR config pin that selects between internal and external arbiter must be pulled
25.MDIC0 is grounded through an 18.2-Ω precision 1% resistor and MDIC1 is connected GV
26.For SGMII mode.
27.Connect to GND.
28.For systems that boot from a local bus (GPCM)-controlled flash, a pull-up on LGPL4 is required.
6.The value of LA[28:31] during reset sets the CCB clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down
7.The value of LALE, LGPL2, and LBCTL at reset set the e500 core clock to CCB clock PLL ratio. These pins require 4.7-kΩ
8.Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or
9.For proper state of these signals during reset, DMA_DACK[1] must be pulled down to GND through a resistor. DMA_DACK[0]

because it has other manufacturing test functions. Therefore, this pin will be described as an I/O for boundary scan.
