Function
Shift to STOP mode after clearing the A/D converter (by clearing bit 7 (ADCS) of the
A/D converter mode register (ADM) to 0). The operating current can be reduced by
clearing bit 0 (ADCE) of the A/D converter mode register (ADM) to 0 at the same time.
To restart from the standby status, clear bit 0 (ADIF) of interrupt request flag register
1L (IF1L) to 0 and start operation.
When rewriting FR2 to FR0, LV1, and LV0 to other than the same data, stop A/D
conversion (ADCS = 0) beforehand.
The above conversion time does not include clock frequency errors.
conversion time, taking clock frequency errors into consideration.
When using a temperature sensor, use the result of the second or later A/D
conversion for temperature sensor 0 (ANI0 side), and the result of the third or later
A/D conversion for temperature sensor 1 (ANI1 side).
Be sure to clear bits 4 to 6 to “0”.
Make sure the period of <2> to <5> is 1
the result of the third and later conversion becomes valid on the sensor 0 side.
<2> can be done between <3> and <4>.
The period from <7> to <10> differs from the conversion time set using bits 5 to 1
(FR2 to FR0, LV1, LV0) of ADM. The period from <9> to <10> is the conversion time
set using FR2 to FR0, LV1, and LV0.
Do not change the AV
sensor detection value does not depend on the AV
problem even if the AV
be stable during a measurement cycle (from <4> to <13>).
Use the result of the second or later A/D conversion for temperature sensor 0 (ANI0
side), and the result of the third or later A/D conversion for temperature sensor 1
(ANI1 side).
Be sure that the voltage to be applied to AV
stated in Table 10-1.
If bit 7 (ADCS) and bit 0 (ADCE) of the A/D converter mode register (ADM) are set to
0, the current will not be increased by the A/D converter even if a voltage is applied to
AV

in Figure 10-25, AV
be reduced by satisfying the following conditions (see the main text).
Observe the rated range of the ANI0 to ANI7 input voltage. If a voltage of AV
higher and AV
an analog input channel, the converted value of that channel becomes undefined. In
addition, the converted values of the other channels may also be affected.
Conflict between A/D conversion result register (ADCR, ADCRH) write and ADCR or
ADCRH read by instruction upon the end of conversion
ADCR or ADCRH read has priority. After the read operation, the new conversion
result is written to ADCR or ADCRH.
Conflict between ADCR or ADCRH write and A/D converter mode register (ADM)
write, analog input channel specification register (ADS), or A/D port configuration
register (ADPC) write upon the end of conversion
ADM, ADS, or ADPC write has priority. ADCR or ADCRH write is not performed, nor
is the conversion end interrupt signal (INTAD) generated.
