M16C/64A Group 5. Electrical Characteristics
Notes:
1. Use when AV
CC
= V
CC1
.
2. When V
CC1
≥ V
CC2
, set as below:
Analog input voltage (AN0 to AN7, ANEX0, and ANEX1)
≤ V
CC1
Analog input voltage (AN0_0 to AN0_7 and AN2_0 to AN2_7) ≤ V
CC2
.
3. When analog input voltage is over reference voltage, the result of A/D conversion is 3FFh.
4. Flash memory rewrite disabled. Except for the analog input pin, set the pins to be measured as input ports and
connect them to V
SS
. See Figure 5.2 “A/D Accuracy Measure Circuit”.
5.1.4 D/A Conversion Characteristics
Notes:
1. This applies when using one D/A converter, with the D/A register for the unused D/A converter set to 00h.
2. The current consumption of the A/D converter is not included. Also, the I
VREF
of the D/A converter will flow even
if the ADSTBY bit in the ADCON1 register is 0 (A/D operation stopped (standby)).
