Notes:
1. All multiplexed signals are listed only once and do not re-occur. For example, LCS5/DMA_REQ2 is listed only once in the local
2. Recommend a weak pull-up resistor (2–10 KΩ) be placed on this pin to OV
4. This pin is an open drain signal.
5. This pin is a reset configuration pin. It has a weak internal pull-up P-FET which is enabled only when the processor is in the
6. Treat these pins as no connects (NC) unless using debug address functionality.
7. 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
8. 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
9. Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or
11.This output is actively driven during reset rather than being three-stated during reset.
12.These JTAG pins have weak internal pull-up P-FETs that are always enabled.
13.These pins are connected to the V
14.Internal thermally sensitive resistor. These two pins are not ESD protected.
17.. The value of PA[0:4] during reset set the QE clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down
19. 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
20. This pin is only an output in FIFO mode when used as Rx Flow Control.
24. Do not connect.
25.These are test signals for factory use only and must be pulled up (100 - 1 K) to OVDD for normal machine operation.
26. Independent supplies derived from board VDD.
27. Recommend a pull-up resistor (~1 K.) be placed on this pin to OV
29. The following pins must NOT be pulled down during power-on reset: HRESET_REQ, TRIG_OUT/READY/QUIESCE,

reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kΩ pull-down resistor. However, if the
signal is intended to be high after reset, and if there is any device on the net which might pull down the value of the net at reset,
then a pullup or active driver is needed.
