Sleep modes
In normal operation, all clock domains are active, allowing software execution and peripheral
operation. When the CPU is idle, it is possible to switch off the CPU clock and optionally other
clock domains to save power. This is activated by the sleep instruction, which takes the sleep
mode index number as argument.
The sleep instruction will halt the CPU and all modules belonging to the stopped clock domains.
The modules will be halted regardless of the bit settings of the mask registers.
Oscillators and PLLs can also be switched off to save power. Some of these modules have a rel-
atively long start-up time, and are only switched off when very low power consumption is
required.
The CPU and affected modules are restarted when the sleep mode is exited. This occurs when
an interrupt triggers. Note that even if an interrupt is enabled in sleep mode, it may not trigger if
the source module is not clocked.
The following sleep modes are supported. These are detailed in
•Idle: The CPU is stopped, the rest of the chip is operating. Wake-up sources are any interrupt.
•Frozen: The CPU and HSB modules are stopped, peripherals are operating. Wake-up sources
are any interrupts from PB modules.
•Standby: All synchronous clocks are stopped, but oscillators and PLLs are running, allowing
quick wake-up to normal mode. Wake-up sources are RTC or external interrupt (EIC), external
reset or any asynchronous interrupts from PB modules.
•Stop: As Standby, but Oscillator 0 and 1, and the PLLs are stopped. 32 KHz (if enabled) and
RC oscillators and RTC/WDT will still operate. Wake-up are the same as for Standby mode.
•DeepStop: All synchronous clocks, Oscillator 0 and 1 and PLL 0 and 1 are stopped. 32 KHz
oscillator can run if enabled. RC oscillator still operates. Bandgap voltage reference and BOD is
turned off. Wake-up sources are RTC, external interrupt in asynchronous mode, external reset
or any asynchronous interrupts from PB modules.
•Static: All oscillators, including 32 KHz and RC oscillator are stopped. Bandgap voltage refer-
ence BOD detector is turned off. Wake-up sources are external interrupt (EIC) in asynchronous
mode only, external reset pin or any asynchronous interrupts from PB modules.
