9.2 Hibernation
Hibernation allows shutting down a part or the complete system. Hibernation can be terminated by every possible interrupt of the PMU. The
interrupt has to be enabled before going to hibernation.
Table 11. Hibernation
State
Enter via GPIO
Enter via SW
Hibernation
Leave
Description
To enter hibernation mode the following settings have to be done:
- Enable just these IRQ sources which should lead to leave hibernation mode.
- Make sure that IRQ is inactive (IRQ flags get cleared by Reg 23h-26h readings.
- Set the GPIO to input
- Define which regulators should be kept powered and enter hibernation by writing to Reg 1Ch_0x04 + Reg
17h-4. This register MUST NOT be read back!!!
- Drive the selected GPIO to LOW.
Note that hibernation will shutdown regulators which are not in the keep list of the mentioned Reg 17h-4 writing and
are part of the power-up sequence.

are part of the power-up sequence.
VDD27 chip supply is kept ON
All other regulators are switched OFF dependent on the KEEP-Bits
XRES goes active (can be disabled in the boot ROM) and PWRGOOD goes inactive
The chip will come out of Hibernation with
- IRQ activation or
- GPIO control
Start-Up sequence is provided defined by the boot ROM.
9.3 Supervisor
This supervisor function can be used for automatic detection of VSUP brown out or junction over-temperature condition.
9.3.1
VSUP Supervision
The VSUP supervision has a selectable level. If the shutdown is not enabled an interrupt can be generated.
9.3.2
VDD27 Supervision
If VDD27 reaches the “programmed level of VDD27” -10% for typ. 3ms, the PMU shuts down automatically. If the shutdown is not enabled an
interrupt can be generated.
9.3.3
Junction Temperature Supervision
The temperature supervision level can also be set by 5 bits (120 to –15oC). If the temperature reaches this level, an interrupt can be generated.
The over-temperature shutdown level is always 20oC higher. This shutdown can be disabled in Reg. 20h.
9.3.4
Power Rail Monitoring
The 3 DCDC regulators have an extra monitor which observes the output voltage of the regulators. This power rail monitors are independent
from the 10bit ADC. To activate these please see related registers. For a shut down the voltage of the regulator has to be 10% or more below the
programmed value for more than 3ms.
