14.4.3 Cautions
446
Observe the following cautions when using the D/A converter of the V850ES/JF3-L.
(1) Do not change the set value of the DA0CS0 register while the trigger signal is being issued in the real-time
(2) Before changing the operation mode, be sure to clear the DA0M.DA0CE0 bit to 0.
(3) Make sure that AV
(4) Apply power to AV
(5) No current can be output from the ANO0 pin because the output impedance of the D/A converter is high.
(6) Because the D/A converter stops operation in the STOP mode, the ANO0 pin goes into a high-impedance state,
output mode.
When connecting a resistor of 2 MΩ or less, insert a JFET input operational amplifier between the resistor and
the ANO0 pin.
and the power consumption can be reduced.
However, the pin status is kept in the IDLE1, IDLE2, or subclock operation mode. To reduce the power
consumption, therefore, clear the DA0M.DA0CE0 bit to 0.
