To start AD conversion, write 1 to ADMOD0<ADS> in AD mode control register 0, or
Writing 1 to ADMOD0<ADS> during AD conversion restarts conversion. At that

The 4 AD conversion modes are:
The ADMOD0<REPEAT> and ADMOD0<SCAN> settings in AD mode control
Completion of AD conversion triggers an INTAD AD conversion end interrupt
Setting ADMOD0<REPEAT> and ADMOD0<SCAN> to 00 selects channel fixed
single conversion mode.
In this mode, data on one specified channel is converted once only. When the
conversion has been completed, the ADMOD0<EOCF> flag is set to 1, ADMOD0
<ADBF> is cleared to 0, and an INTAD interrupt request is generated.
Setting ADMOD0<REPEAT> and ADMOD0<SCAN> to 01 selects channel scan
single conversion mode.
In this mode, data on the specified scan channels is converted once only. When

ADMOD0<ADBF> is cleared to 0, and an INTAD interrupt request is generated.
Setting ADMOD0<REPEAT> and ADMOD0<SCAN> to 10 selects channel fixed
repeat conversion mode.
In this mode, data on one specified channel is converted repeatedly. When

ADMOD0<ADBF> is not cleared to 0 but held 1. INTAD interrupt request
generation timing is determined by the setting of ADMOD0<ITM0>.
Setting <ITM0> to 0 generates an interrupt request every time an AD conversion
is completed.
Setting <ITM0> to 1 generates an interrupt request on completion of every fourth
conversion.
