12.4.3 Cautions
298
Observe the following cautions when using the D/A converter of the V850ES/SA2 and V850ES/SA3.
(1) Do not change the set value of the DACSn register while the trigger signal is being issued in the real-time
(2) Before changing the operation mode, be sure to clear DACEn to 0.
(3) When using only one channel of the D/A converter, connect the pins that are not used as analog outputs to
(4) When using the P80/ANO0 and P81/ANO1 pins as port pins (when not using the D/A converter), make sure
(5) When not using the D/A converter in the standby mode, clear the DACS bit to 0, and then change to the
(6) Make sure that V
(7) Apply power to AV
(8) No current can be output from the ANOn pin (n = 0, 1) because the output impedance of the D/A converter is
