Analog Reference Voltage
Selecting the Analog Input Channel
(1) Normal AD conversion mode
(2)Top-priority AD conversion mode
The "H" level of the analog reference voltage shall be applied to the VREFH pin, and the
"L" level shall be applied to the VREFL pin. By writing "0" to the ADMOD1<VREFON> bit,
a switched-on state of VREFH-VREFL can be turned into a switched-off state. To start AD
conversion, make sure that you first write "1" to the <VREFON> bit, wait for 3 μs during
which time the internal reference voltage should stabilize, and then write "1" to the
ADMOD0<ADS> bit.
How the analog input channel is selected is different depending on A/D converter
operation mode used.
•
One channel is selected from analog input pins AIN0 through AIN11 by setting
ADMOD1<ADCH3 to 0> to an appropriate setting.
•
One scan mode is selected from 12 scan modes by setting ADMOD1<ADCH3 to 0> and
ADSCN to appropriate settings.
One channel is selected from analog input pins AIN0 through AIN11 by setting
ADMOD2<HPADCH3 to 0> to an appropriate setting.
After a reset, ADMOD0<SCAN> is initialized to "0" and ADMOD1<ADCH3:0> is
initialized to "0000." This initialization works as a trigger to select a fixed channel input
through the AN0 pin. The pins that are not used as analog input channels can be used as
ordinary input ports.
If top-priority AD conversion is activated during normal AD conversion, normal AD
conversion is discontinued, top-priority AD conversion is executed and completed, and
then normal AD conversion is resumed.
Example:
A case in which repeat-scan conversion is ongoing at channels AIN0 through AIN3 with
ADMOD0<REPEAT:SCAN> set to "11" and ADMOD1<ADCH3:0> set to 0011, and
top-priority
ADMOD2<HPADCH3:0>=1100.
If the analog input channel is used in a fixed state (ADMOD0<SCAN>="0"):
If the analog input channel is used in a scan state (ADMOD0<SCAN>="1"):
