Power-up and Startup Time
To convert correct values, both references and ADC have to be powered-up correctly, otherwise
wrong values will be converted until the end of the start-up time.
When in sleep mode, the HOT start-up sequence is performed each time a conversion or a
sequence is triggered thanks to the SOCB bit in the SEQCFGx register. Indeed, the ADC analog
block is powered off while not used.
The end of the power-up sequence can be read from the Start-Up Time Done (SUTD) bit of the
SR register. This bit is set by hardware at the end of the start-up sequence and cleared by soft-
ware by writing a '1' in the SUTD bit of the SCR register. It is also cleared by hardware when the
ADCIFA is turned off then on by clearing and setting the ADCEN bit of the CFG register.
Figure 36-10. Power-Up Sequence
• Cold start-up: References needs 1 ms max to establish.
• Hot start-up: Once references are up, 24 CkADC clock periods are needed.
