1.7.1
The ADC module includes four external trigger inputs ETRIG0, ETRIG1, ETRIG2, and ETRIG3. The
external trigger allows the user to synchronize ADC conversion to external trigger events.
shows the connection of the external trigger inputs.
Consult the ATD block description for information about the analog-to-digital converter module. ATD
block description refererences to freeze mode are equivalent to active BDM mode.
1.7.2
Further to the 16 externally available channels, ADC0 features an extra channel[17] that is connected to
the internal temperature sensor at device level. To access this channel ADC0 must use the channel
encoding SC:CD:CC:CB:CA = 1:0:0:0:1 in ATDCTL5. For more temperature sensor information, please
