5.15.3 VDH SUPPLY OVERVOLTAGE PROTECTION
(Submit Feedback)The VDH supply overvoltage protection is active when setting the VDHOVSD bit to
‘1’. If a VVDH > VVDH_OV_Set event occurs,
the device will switch the GDU to GDU Standby mode (when in GDU Normal mode) and the
charge pump will be deactivated (as long as the overvoltage condition is valid).
If the VDHOVSD bit is set to ‘0’, the device will not react to the
overvoltage event, the GDU will remain in Normal mode and the charge pump will keep
operating. Only an NIRQ interrupt event will be generated, presuming the VDHOVECE bit is
set to ‘1’.
The device will set the status register bit (VDHOV, see the SIR1
Register), presuming the VDHOVECE bit is set to ‘1’, and an NIRQ
interrupt event will be generated. Set the VDHOVECE bit to ‘0’ to
disable VDH overvoltage event capture.
VDH overvoltage monitoring is only active in Normal mode.
