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
2. Recommend a weak pull-up resistor (2–10 kΩ) be placed on this pin to OV
3. TEST_SEL0 must be pulled-high, TEST_SEL1 must be tied to ground.
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 MPC8555E is in
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
8. The value of LALE and LGPL2 at reset set the e500 core clock to CCB Clock PLL ratio. These pins require 4.7-kΩ pull-up
9. Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or
10. This pin functionally requires a pull-up resistor, but during reset it is a configuration input that controls 32- vs. 64-bit PCI
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.
15. No connections should be made to these pins.
16. These pins are not connected for any functional use.
17. PCI specifications recommend that a weak pull-up resistor (2–10 kΩ) be placed on the higher order pins to OV
18. If this pin is connected to a device that pulls down during reset, an external pull-up is required to that is strong enough to
19. Recommend a pull-up resistor (~1 kΩ) be placed on this pin to OV
20. These are test signals for factory use only and must be pulled up (100Ω το 1kΩ) to OV
21. If this signal is used as both an input and an output, a weak pull-up (~10kΩ) is required on this pin.
22. MSYNC_IN and MSYNC_OUT should be connected together for proper operation.

the reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kΩ pull-down resistor. If an
external device connected to this pin might pull it down during reset, then a pull-up or active driver is needed if the signal is
intended to be high during reset.
