User manual
4.8.1 Sleep mode
4.8.2 Deep Sleep mode
The LPC17xx supports a variety of power control features: Sleep mode, Deep Sleep
mode, Power-down mode, and Deep Power-down mode. The CPU clock rate may also be
controlled as needed by changing clock sources, re-configuring PLL values, and/or
altering the CPU clock divider value. This allows a trade-off of power versus processing
speed based on application requirements. In addition, Peripheral Power Control allows
shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power
consumption by eliminating all dynamic power use in any peripherals that are not required
for the application.
Entry to any reduced power mode begins with the execution of either a WFI (Wait For
Interrupt) or WFE (Wait For Exception) instruction by the Cortex-M3. The Cortex-M3
internally supports two reduced power modes: Sleep and Deep Sleep. These are selected
by the SLEEPDEEP bit in the cortex-M3 System Control Register. Power-down and Deep
Power-down modes are selected by bits in the PCON register. See
register contains flags that indicate whether entry into each reduced power mode actually
occurred.
The LPC17xx also implements a separate power domain in order to allow turning off
power to the bulk of the device while maintaining operation of the Real Time Clock.
Reduced power modes have some limitation during debug, see
information.
Note: Sleep mode on the LPC17xx corresponds to the Idle mode on LPC2xxx series
devices. The name is changed because ARM has incorporated portions of reduced power
mode control into the Cortex-M3. LPC17xx documentation uses the Cortex-M3
terminology where applicable.
When Sleep mode is entered, the clock to the core is stopped, and the SMFLAG bit in
PCON is set, see
sequence but re-enabling the clock to the ARM core.
In Sleep mode, execution of instructions is suspended until either a Reset or an interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
The GPDMA may operate in Sleep mode to access AHB SRAMs and peripherals with
GPDMA support, but the GPDMA cannot access the flash memory or the main SRAM,
which are disabled in order to save power.
Wake-up from Sleep mode will occur whenever any enabled interrupt occurs.
Note: Deep Sleep mode on the LPC17xx corresponds to the Sleep mode on LPC23xx
and LPC24xx series devices. The name is changed because ARM has incorporated
portions of reduced power mode control into the Cortex-M3. LPC17xx documentation
uses the Cortex-M3 terminology where applicable.
