Description
Reserved.
1 = EEPROM is unlocked and its contents can be written.
1 = downloaded EEPROM contents are incorrect.
1 = the resistor on the ADD pin has a value that can cause an error in the address assignment
(the address falls too close to the threshold between two addresses).
1 = input voltage is higher than the high line threshold.
1 = the threshold set for the comparator on the ILIM pin has been crossed.
1 = external synchronization frequency is locked.
This flag is a programmable combination of other internal flags and refers to the condition of
the input voltage. A value of 1 means that the output of the AC_OK pin is low.
Description
Reserved.
1 = input power has dropped below the threshold for low power mode operation.
1 = fast loop compensation filter is in use.
1 = an overvoltage condition is present on the VCORE rail.
1 = an overvoltage condition is present on the VDD rail.
1 = an undervoltage condition is present on the VDD rail.
Reserved.
Description
Return the eight MSBs of the PWM value (10 bits).
Description
Return the measured period on the VAC pin signal. Each LSB corresponds to 163.84 μs.
Description
Return the measured temperature in ADC 12-bit format.
Description
1 = negative offset trim is introduced.
0 = positive offset trim is introduced.
This value calibrates the power meter offset at the high line input voltage. Each LSB corresponds
to 0.0625/128 of the full input power.
