Power Management
8.1
This chapter explains the low-power operation of the MCF5271.
8.1.1
The following features support low-power operation.
8.2
The PM programming model consists of one register:
8.2.1
The following subsection describes the PM registers.
Freescale Semiconductor
• Four modes of operation: Run, Wait, Doze, and Stop
• Ability to shut down most peripherals independently
• Ability to shut down the external CLKOUT pin
• The low-power control register (LPCR) specifies the low-power mode entered when the

S = CPU supervisor mode access only. User mode accesses to supervisor only addresses have no effect and result
in a cycle termination transfer error.
The CRSR, CWCR, and CWSR are described in the System Control Module. They are shown here only to warn
against accidental writes to these registers when accessing the LPICR.
The CCR is described in the Chip Configuration Module. It is shown here only to warn against accidental writes to
this register when accessing the LPCR.
