The signals that serve alternate functions as configuration input signals during system reset are
summarized in
Chapter 4, “Reset, Clocking, and Initialization.”
Note that throughout this document, the reset configuration signals are described as being sampled at the
negation of HRESET. However, there is a setup and hold time for these signals relative to the rising edge
of HRESET, as described in the MPC8544E Integrated Processor Hardware Specifications. Note that the
PLL configuration signals have different setup and hold time requirements than the other reset
configuration signals.
The reset configuration signals are multiplexed with other functional signals. The values on these signals
during reset are interpreted to be logic one or zero, regardless of whether the functional signal name is
defined as active-low. Most of the reset configuration signals have internal pull-up resistors so that if the
signals are not driven, the default value is high (a one), as shown in the table. Some signals do not have
