MPC8572EAMC Functional Description

MPC8572E Power-On Reset Configuration (POR Config)
The power-on reset configuration of the PowerQUICC? III family devices uses dedicated input pins that
are sampled during the assertion of reset to configure the processor. The master reset signal is generated
locally on-board from the reset circuitry, controlled by the System CPLD, as shown in Figure 5-8 .
Figure 5-8. MPC8572E POR Configuration
All of the POR configuration signals are handled via System CPLD control. Some of the MPC8572EAMC
signals are changeable via a set of DIP switches, whereas others are physically hard-wired on the board to
minimize board space. Some of these signals have an internal pull-up that selects a default state. Table 5-7
details all POR configuration pins and their specific usage on the MPC8572EAMC board.
