15.25.3 GPIO_VDD_INTR
Description:
Supply detection interrupt register
Address:
0x40314014
Offset:
0x4014
Retention:
Retained
IsDeepSleep:
No
Comment:
An interrupt cause is cleared (set to '0') by writing a '1' to the corresponding bit field. It is not
recommended to write 0xFF to clear all interrupt causes, as a new interrupt cause may have
occurred between reading the register and clearing. Note that the interrupt cause fields and
the associated interrupt provide DeepSleep functionality (interrupt causes can be set to '1' and
cause the system to wake up from DeepSleep power mode). This register is set whenever a
supply ramp up or ramp down is detected. Some bits may be set after system power-up,
depending on power supply sequencing.
Default:
0x0

The VDDD supply is always present during operation
so a supply transition can not occur. This bit will
always read back '1'.
