Notes:
1. OV
2. Unused address pins must be pulled down to GND and corresponding address parity pins pulled up to OV
3. These pins require weak pull-up resistors (for example, 4.7 KΩ ) to maintain the control signals in the negated state after they
4. This signal selects between MPX bus mode (asserted) and 60x bus mode (negated) and will be sampled at HRESET going
5. This signal must be negated during reset, by pull-up resistor to OV
6. Internal pull up on die.
7. Ignored in 60x bus mode.
8. These signals must be pulled down to GND if unused, or if the MPC7447A is in 60x bus mode.
9. These input signals are for factory use only and must be pulled down to GND for normal machine operation.
10.This test signal is recommended to be tied to HRESET; however, other configurations will not adversely affect performance.
11.These signals are for factory use only and must be left unconnected for normal machine operation. Some pins that were
12.These input signals are for factory use only and must be pulled up to OV
13.This pin can externally cause a performance monitor event. Counting of the event is enabled through software.
14.This signal must be asserted during reset, by pull down to GND or assertion by HRESET, to ensure proper operation.
15.These pins were NCs on the MPC7447, MPC7445, and MPC7441. They may be left unconnected for backward compatibility
16.These pins were OV
17.These pins provide connectivity to the on-chip temperature diode that can be used to determine the die junction temperature
