... NXP Semiconductors The processor state and registers, peripheral registers, and internal SRAM values are preserved throughout Sleep mode and the logic levels of chip pins remain static. The Sleep mode can be terminated and normal operation resumed by either a Reset or certain specific interrupts that are able to function without clocks. Since all dynamic operation of the chip is suspended, Sleep mode reduces chip power consumption to a very low value ...
