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

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.
