Notes
58. STANDBY = 0: System is not in Standby; STANDBY = 1: System is in Standby and Standby programmability is activated.
When requesting standby, a programmable delay (STBYDLY) of 0 to 3 clock cycles of the 32 kHz clock is applied before
actually going into standby (i.e. before turning off some supplies). No delay is applied when coming out of standby.

REGULATOR MODE CONTROL
The regulators with embedded pass devices (VDIG, VPLL, VIOHI, VUSB, VUSB2, and VAUDIO) have an adaptive biasing
scheme, thus, there are no distinct operating modes such as a Normal mode and a Low-power mode. Therefore, no specific
control is required to put these regulators in a Low-power mode.
The regulators with external pass devices (VSD, VVIDEO, VGEN1, and VGEN2) can also operate in a Normal and Low-power
mode. However, since a load current detection cannot be performed for these regulators, the transition between both modes is
not automatic and is controlled by setting the corresponding mode bits for the operational behavior desired.
The regulators VGEN3 and VCAM can be configured for using the internal pass device or external pass device as explained
in Power Control System . For both configurations, the transition between Normal and Low-power modes is controlled by setting
the VxMODE bit for the specific regulator. Therefore, depending on the configuration selected, the automatic Low-power mode
is available.
The regulators can be disabled and the general purpose outputs can be forced low when going into Standby as described
previously. Each regulator and GPO has an associated SPI bit for this. When the bit is not set, STANDBY is of no influence. The
actual operating mode of the regulators as a function of STANDBY is not reflected through the SPI. In other words, the SPI will
read back what is programmed, not the actual state.

Notes
59. This table is valid for regulators with an external pass device
60. STANDBY refers to a Standby event as described earlier
For regulators with internal pass devices and general outputs, the previous table can be simplified.
