the same frequency of MC_PLL_CLK or is half of MC_PLL_CLK, depending on the
value of the bit ADCLKSEL.
● CTUEN field in the MCR: Enables or disables CTU control mode
● Registers CDR[16..95] not used

23.2 Introduction
The analog-to-digital converter (ADC) block provides accurate and fast conversions for a
wide range of applications.
The ADC contains advanced features for normal or injected conversion. It provides support
for eDMA (direct memory access) mode operation. A conversion can be triggered by
software or hardware (Cross Triggering Unit or PIT).
The mask registers present within the ADC can be programmed to configure the channel to
be converted.
Analog watchdogs allow continuous hardware monitoring.
