(3) Setting
218
The setting methods are described below.
<Change the channel>
<Complete A/D conversion>
When used as normal A/D conversion operation
<1> Set bit 0 (ADCS2) of the A/D converter mode register (ADM) to 1.
<2> Select the channel and conversion time using bits 2 to 0 (ADS2 to ADS0) of the analog input channel
<3> Set bit 7 (ADCS) of ADM to 1 to start the A/D conversion.
<4> An interrupt request signal (INTAD) is generated.
<5> Transfer the A/D conversion data to the A/D conversion result register (ADCR).
<6> Change the channel using bits 2 to 0 (ADS2 to ADS0) of ADS to start the A/D conversion.
<7> An interrupt request signal (INTAD) is generated.
<8> Transfer the A/D conversion data to the A/D conversion result register (ADCR).
<9> Clear ADCS to 0.
<10> Clear ADCS2 to 0.
Cautions 1. Make sure the period of <1> to <3> is 1 s or more.
specification register (ADS) and bits 5 to 1 (FR2 to FR0, ADHS1, ADHS0) of ADM.
2. It is no problem if the order of <1> and <2> is reversed.
3. <1> can be omitted. However, do not use the first conversion result after <3> in this
4. The period from <4> to <7> differs from the conversion time set using bits 5 to 1 (FR2 to
case.
FR0, ADHS1, ADHS0) of ADM. The period from <6> to <7> is the conversion time set
using FR2 to FR0, ADHS1, and ADHS0.
