Mark Bundgus / LPC1114_Deep_Power_Down

During Deep power-down mode, the contents of the SRAM and registers are not retained except for a small amount of data which can be stored in five 32-bit general purpose registers of the power management unit block. All functional pins are tri-stated in Deep power-down mode except for the WAKEUP pin.

bundgus 0:959f4e23f133 10 In Deep Power-down mode, power and clocks are shut off to the entire chip with the

bundgus 0:959f4e23f133 18 On the LPC11xx, LPC11xx(L) and LPC11Cxx parts, the RESET /PIO0_0 pin needs to
bundgus 0:959f4e23f133 19 be externally pulled up via 10k – 47k resistor when in deep power-down mode. If the pin
bundgus 0:959f4e23f133 20 is left floating, user will see an increase in current consumption.
