DC-DC Converters 1, 3, 4 and 6 can also be controlled by the device HIBERNATE bit, or by
hardware input signals L_PWR1, L_PWR2 and L_PWR3. Several GPIO pins can be assigned as
L_PWR pins. Each converter can be assigned to one of these three signals, or else to the device
HIBERNATE bit. The signals are active high and each converter’s response to the selected signal is
programmable as defined in Table 72.
Note that, when a GPIO pin is configured as a Hibernate input pin, and this input is asserted, then all
DC-DC Converters will be placed in Hibernate mode.
In order to use GPIO pins as L_PWR pins, they must be configured by setting the respective
GPn_FN, and GPn_DIR bits to the appropriate value (see Section 20).

11 = L_PWR3
Note that Hibernate is also selected
when a GPIO Hibernate input is
asserted.
