(3) When the external supply power to the Q62AD-DGH switches OFF, the A/D
conversion completed flag turns OFF, the digital output values are held as previously,
and A/D conversions stop.
When the external supply power switches ON, A/D conversions resume, and as soon as
all conversion-enabled channels have completed conversions, the A/D conversion
completed flag turns ON.
The processing, such as averaging processing or primary delay filter, starts from the first
time after resumption of A/D conversion.
(1) Error flag (XF) turns ON when a write error occurs.
(2) To clear the error code, set the error clear request (YF) to ON.
