14.4.2 Operation in real-time output mode
as triggers.
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 4-15 Settings When Port Pins Are Used for
D/A conversion is performed using the interrupt request signals (INTTP2CC0 and INTTP3CC0) of TMP2 and TMP3
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 TMP2 and TMP3.
<5> D/A conversion starts when the INTTP2CC0 and INTTP3CC0 signals are generated.
<6> After that, the value set in DA0CSn register is output every time the INTTP2CC0 and INTTP3CC0 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.
