Chapter 19
Global Utilities
This chapter describes the global utilities of the MPC8544E It provides signal descriptions, register
descriptions, and a functional description of these utilities.
19.1
The global utilities block controls power management, I/O device enabling, power-on-reset (POR)
configuration monitoring, general-purpose I/O signal configuration, alternate function select ion for
multiplexed signals, and clock control.
19.2
This section provides an overview of global utilities features.
19.2.1
The following features affect the device’s overall power consumption:
19.2.2
The POR configuration values of all device parameters sampled from pins at reset are available through
memory-mapped registers in the global utilities block.
19.2.3
IRQ[9:11] and LCS[5:7] serve multiple functions that can be selected by configuration registers in the
global utilities block.
19.2.4
The global utilities block also selects the internal clock signal driven on CLK_OUT.
