Top-priority AD conversion. The ADC initiates a normal AD conversion by software
when the ADMOD0<ADS> is set to “1”. It initiates a Top-priority AD conversion by
software when the ADMOD2<HADS> is set to “1”. For a normal AD conversion,
ADMOD1<REPEAT, SCAN> select one of four conversion modes. For a Top-priority
AD conversion, the ADC only supports Fixed-Channel Single Conversion mode.
a normal and Top-priority AD conversion, respectively. When these bits are set to “10”,
a normal or Top-priority AD conversion is triggered by a falling edge applied to
pin. When ADMOD0<TSEL1:0> is set to “00”, a normal AD conversion is triggered by
INTTB00 of 16-Bit Timer interrupt. When ADMOD2<HTSEL1:0> is set to “00”, a
Top-priority AD conversion is triggered by INTTB10 of 16-Bit Timer interrupt. If this
bit is “11”, it is triggered by I2S sampling block. Even when a hardware trigger is
enabled, software starting can be used.

ADMOD0<BUSY> is kept to “1.”
The AD conversion has the two types of normal AD conversion and top-priority AD
Normal AD conversion can be started up by setting ADMOD0<ADS> to “1.”
