D/A conversion is performed using a write operation to the DA0CS0 register as the trigger.
The setting method is described below.
<1> Set the DA0M.DA0MD0 bit to 0 (normal mode).
<2> Set the analog voltage value to be output to the ANO0 pin to the DA0CS0 register.
<3> Set the DA0M.DA0CE0 bit to 1 (D/A conversion enable).
<4> To perform subsequent D/A conversions, write to the DA0CS0 register.
Remark
D/A conversion is performed using an interrupt request signal (INTTP2CC0) of TMP2 as a trigger.
The setting method is described below.
<1> Set the DA0M.DA0MD0 bit to 1 (real-time output mode).
<2> Set the analog voltage value to be output to the ANO0 pin to the DA0CS0 register.
<3> Set the DA0M.DA0CE0 bit to 1 (D/A conversion enable).
<4> Operate TMP2.
<5> D/A conversion starts when the INTTP2CC0 signal is generated.
<6> After that, the value set in the DA0CS0 register is output every time the INTTP2CC0 signal is generated.
Remarks 1. The output value of the ANO0 pin up to <5> above is undefined.
Steps <1> and <2> above constitute the initial settings.
D/A conversion starts when this setting is performed.
The previous D/A conversion result is held until the next D/A conversion is performed.
Steps <1> to <3> above constitute the initial settings.
2. For the output values of the ANO0 pin in the HALT, IDLE1, IDLE2 and STOP modes, see CHAPTER 21
