Mode 5
Same as mode 1, but with absolute voltage levels and without a validation check.
P2942[0] - POWF_VOn is used to define the power failure detection limit. P2942[1]
- POWF_VRef is used to define the voltage setpoint. The configured values will not
be checked to see if they are valid. The user themselves will be responsible for
ensuring that the values entered make sense.
Mode 6
Same as mode 2, but with absolute voltage levels and without a validation check.
P2942[0] - POWF_VOn is used to define the power failure detection limit. P2942[1]
- POWF_VRef is used to define the voltage setpoint. The configured values will not
be checked to see if they are valid. The user themselves will be responsible for
ensuring that the values entered make sense.
Mode 7
Same as mode 6, but with pulse operation.
P2942[0] - POWF_VOn is used to define the power failure detection limit. P2942[1]
- POWF_VRef is used to define the voltage setpoint. The configured values will not
