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 DA0M.DA0MDn bit to 0 (normal mode).
<2> Set the analog voltage value to be output to the ANOn pin to the DA0CSn register.
<3> Set the DA0M.DA0CEn bit to 1 (D/A conversion enable).
<4> To perform subsequent D/A conversions, write to the DA0CSn register.
Remarks 1. For the alternate-function pin settings, see Table 4-20 Using Port Pins as Alternate-Function Pins.
D/A conversion is performed using the interrupt request signals (INTTAA2CC0 and INTTAA3CC0) of TAA2 and TAA3
The setting method is described below.
<1> Set the DA0M.DA0MDn bit to 1 (real-time output mode).
<2> Set the analog voltage value to be output to the ANOn pin to the DA0CSn register.
<3> Set the DA0M.DA0CEn bit to 1 (D/A conversion enable).
<4> Operate TAA2 and TAA3.
<5> D/A conversion starts when the INTTAA2CC0 and INTTAA3CC0 signals are generated.
<6> After that, the value set in DA0CSn register is output every time the INTTAA2CC0 and INTTAA3CC0 signals are
Remarks 1. The output values of the ANO0 and ANO1 pins up to <5> above are 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.
generated.
2. n = 0, 1
2. For the output values of the ANO0 and ANO1 pins in the HALT, IDLE1, IDLE2, and STOP modes, see
3. For the alternate-function pin settings, see Table 4-20 Using Port Pins as Alternate-Function Pins.
