Function
Be sure to clear bits 3 to 6 to “0”.
Set a channel to be used for A/D conversion in the input mode by using port mode
registers 2 (PM2).
Do not set the pin that is set by ADPC as digital I/O by ADS.
Set a channel to be used for A/D conversion in the input mode by using port mode
registers 2 (PM2).
Do not set the pin that is set by ADPC as digital I/O by ADS.
When using all ANI0/P20 to ANI7/P27 pins as digital I/O (D), the setting can be done
by ADPC4 to ADPC0 = either 01000 or 10000.
P20/ANI0 to P27/ANI7 are set as analog inputs in the order of P27/ANI7, …,
P20/ANI0 by the A/D port configuration register (ADPC). When using P20/ANI0 to
P27/ANI7 as analog inputs, start designing from P27/ANI7.
If a pin is set as an analog input port, not the pin level but “0” is always read.
Make sure the period of <2> to <6> is 1
Make sure the period of <2> to <6> is 1
<2> may be done between <3> and <5>.
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.
The temperature sensor cannot be used when low current consumption mode is set
(RMC = 5AH) or when the internal high-speed oscillator has been stopped
(HIOSTOP = 1 (bit 0 of CSC register)). The temperature sensor can operate as long
as the internal high-speed oscillator operates (HIOSTOP = 0), even if it is not
selected as the CPU/peripheral hardware clock source.
Setting of the A/D port configuration register (ADPC), port mode register 2 (PM2) and
port register 2 (P2) is not required when using the temperature sensor. There is no
problem if the pin function is set as digital I/O.
Set the conversion times so as to satisfy the following condition. f
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>).
