20.7
When using the A/D converter, note the following points.
20.7.1
Operation of the A/D converter can be disabled or enabled using the standby control register. The
initial setting is for operation of the A/D converter to be halted. Register access is enabled by
clearing module standby mode. For details, see section 25, Power-Down Modes.
20.7.2
Permanent damage to the LSI may result if the following voltage ranges are exceeded.
1. Analog input range
2. AVcc and AVss input voltages
3. Setting range of AVref input voltage
20.7.3
In board design, digital circuitry and analog circuitry should be as mutually isolated as possible,
and layout in which digital circuit signal lines and analog circuit signal lines cross or are in close
proximity should be avoided as far as possible. Failure to do so may result in incorrect operation
of the analog circuitry due to inductance, adversely affecting A/D conversion values.
Digital circuitry must be isolated from the analog input signals (AN0 to AN7), analog reference
voltage (AVref), and analog power supply (AVcc) by the analog ground (AVss). Also, the analog
ground (AVss) should be connected at one point to a stable digital ground (PVss) on the board.

During A/D conversion, voltages on the analog input pins ANn should not go beyond the
following range: AVss ≤ ANn ≤ AVcc (n = 0 to 7).
Input voltages AVcc and AVss should be PVcc − 0.3 V ≤ AVcc ≤ PVcc and AVss = PVss. Do
not leave the AVcc and AVss pins open when the A/D converter or D/A converter is not in use
and in software standby mode. When not in use, connect AVcc to the power supply (PVcc)
and AVss to the ground (PVss).
Set the reference voltage range of the AVref pin as 3.0 V ≤ AVref ≤ AVcc.
