Notes:
1.
OVDD supplies power to the processor bus, JTAG, and all control signals except the L3 cache controls
(L3CTL[0:1]); GVDD supplies power to the L3 cache interface (L3ADDR[0:17], L3DATA[0:63], L3DP[0:7],
L3_ECHO_CLK[0:3], and L3_CLK[0:1]) and the L3 control signals L3_CNTL[0:1]; and VDD supplies power to the
processor core and the PLL (after filtering to become AVDD). For actual recommended value of Vin or supply
voltages, see Table 4.
2.
These input signals are for factory use only and must be pulled up to OVDD for normal machine operation.
3.
To program the processor interface I/O voltage, connect BVSEL to either GND (selects 1.8 V) or to HRESET
(selects 2.5 V). To program the L3 interface, connect L3VSEL to either GND (selects 1.8 V) or to HRESET
(selects 2.5 V) or to HRESET (selects 1.5 V). If used, pulldown resistors should be less than 250
.
4.
Ignored in 60x bus mode.
5.
This signal selects between MPX bus mode (asserted) and 60x bus mode (negated) and will be sampled at
HRESET going high.
6.
This signal must be negated during reset, by pull-up to OVDD or negation by HRESET (inverse of HRESET), to
ensure proper operation.
7.
Internal pull-up on die.
8.
These pins require weak pull-up resistors (for example, 4.7 k
) to maintain the control signals in the negated
state after they have been actively negated and released by the MPC7455 and other bus masters.
9.
These input signals for factory use only and must be pulled down to GND for normal machine operation.
10. This pin can externally cause a performance monitor event. Counting of the event is enabled via software.
11. Unused address pins must be pulled down to GND.
12. This test signal is recommended to be tied to HRESET; however, other configurations will not adversely affect
performance.
13. These signals must be pulled down to GND if unused or if the MPC7455 is in 60x bus mode.
14. This signal must be asserted during reset, by pull-down to GND or assertion by HRESET, to ensure proper
operation.
15. Power must be supplied to GVDD, even when the L3 interface is disabled or unused.
16. These signals are for factory use only and must be left unconnected for normal machine operation.
