Note
Description
When DC offset error is detected (when either one of capacitors is
leaking, or an improper connection or another error is detected)
When DC offset error is not detected (when none of capacitors leak,
no improper connection or other error is detected)
When improper connection or other DC offset errors are detected.
When improper connection or other DC offset errors are not detected.
When detecting improper connection or other DC offset errors, clears
detection data. (Clear E2PROM)
When detecting capacitor leak, provides information on the number
of capacitor leaks. (0~4)
When detecting capacitor leak, clears the number of capacitor leaks.
