D/A conversion is performed using a write operation to the DA0CSn register as the trigger.
The setting method is described below.
<1> Set the PM1n bit to 1 (input mode).
<2> Clear the DA0M.DA0MDn bit to 0 (normal mode).
<3> Set the analog voltage value to be output to the ANOn pin to the DA0CSn register.
<4> Set the DA0M.DA0CEn bit to 1 (D/A conversion enable).
<5> To change the analog voltage value, write to the DA0CSn register.
Remarks 1. For the alternate-function pin settings, refer to Table 4-15 Settings When Pins Are Used for
D/A conversion is performed using the interrupt request signal of TMP2 or TMP3 (INTTP2CC0 or INTTP3CC0) as
The setting method is described below.
<1> Set the PM1n bit to 1 (input mode).
<2> Set the DA0M.DA0MDn bit to 1 (real-time output mode).
<3> Set the analog voltage value to be output to the ANOn pin to the DA0CSn register.
<4> Set the DA0M.DA0CEn bit to 1 (D/A conversion enable).
<5> Operate TMP2 and TMP3.
<6> The D/A converted analog voltage value is output from the ANOn pin when the INTTP2CC0 or INTTP3CC0
<7> After that, the value set to the DA0CSn register is output from the ANOn pin every time the INTTP2CC0 or
Remarks 1. The output values of the ANO0 and ANO1 pins up to <6> above are undefined.
Steps <2> and <3> above constitute the initial settings.
The D/A converted analog voltage value is output from the ANOn pin when this setting is performed.
The analog voltage value set immediately before is held until the next write operation is performed.
Steps <2> to <4> above constitute the initial settings.

Set the analog voltage value to be output to the DA0CSn register next, before the next INTTP2CC0 or
INTTP3CC0 signal is generated.
INTTP3CC0 signal is generated.
