3.22.2 Operation
3.22.2.1 Analog Reference Voltages
Apply the analog reference voltage's “H” level side to the VREFH pin and the “L”
level side to the VREFL pin.
3.22.2.2 Selecting Analog Input Channels
Selecting an analog input channel depends on the operation mode of the AC
converter.
(1)
For normal AD conversion
When using an analog input channel in fix mode, select one channel from the AN0 to
AN5 pins by setting (ADMOD1<SCAN> = “0”) ADMOD1<ADCH2:0>.
When using an analog input channel in scan mode, select one scan mode from the six
scan modes by setting (ADMOD1<SCAN>
=
“1”) ADMOD1 <ADCH2:0>.
(2)
For top-priority AD conversion
Select one channel from the analog input pins AN0 to AN5 by setting
ADMOD3<HADCH2:0>.
After reset, ADMOD1<SCAN> is initialized to “0” and ADMOD1<ADCH2:0> to
“000”. Since these settings are used for channel selection, the channel fixed input with
the AN0 pin will be selected. Pins not used as analog input channels can be used as
normal ports.
