11.4.3 Cautions
(1) The digital port I/O function, which is the alternate function of the ANO0 and ANO1 pins, does not operate during
(2) Do not read/write the P11 register and do not change the setting of the PM11 register during D/A conversion
(3) It is recommended that both the ANO0 and ANO1 pins be used as analog output pins or digital I/O pins, that is,
(4) In the real-time output mode, set the DACSn register value before the timer trigger is generated. In addition, do
(5) Before changing the operation mode, be sure to clear the DACEn bit of the DAM register to 0 (D/A conversion
(6) When using the port that functions alternately as the ANO0 or ANO1 pin, use it as the port input with few level
(7) Stop the conversion performed by the D/A converter when supplying AV
(8) Because the D/A converter stops operation in the STOP mode, the ANO0 and ANO1 pins go into a high-

keeping the wiring length as short as possible (for high impedance). If the wiring becomes too long, take
necessary actions such as surrounding with a ground pattern.
