Chapter 4
Reset, Clocking, and Initialization
This chapter describes the reset, clocking, and some overall initialization of the MPC8536E, including a
definition of the reset configuration signals and the options they select. Additionally, the configuration,
control, and status registers are described. Note that other chapters in this book may describe specific
aspects of initialization for individual blocks.
4.1
The reset, clocking, and control signals provide many options for device operation. Additionally, many
modes are selected with reset configuration signals during a hard reset (assertion of HRESET).
