Analog-to-digital converter (ADC)
RM0008
Bits 19:15 JSQ4[4:0] : 4th conversion in injected sequence
These bits are written by software with the channel number (0..17) assigned as the 4th in
the sequence to be converted.
Note: Unlike a regular conversion sequence, if JL[1:0] length is less than four, the channels
are converted in a sequence starting from (4-JL). Example: ADC_JSQR[21:0] = 10
00011 00011 00111 00010 means that a scan conversion will convert the following
channel sequence: 7, 3, 3. (not 2, 7, 3)
Bits 14:10 JSQ3[4:0]: 3rd conversion in injected sequence
Bits 9:5 JSQ2[4:0] : 2nd conversion in injected sequence
Bits 4:0 JSQ1[4:0] : 1st conversion in injected sequence
11.12.13 ADC injected data register x (ADC_JDRx) (x= 1..4)

Bits 31:16 ADC2DATA[15:0]: ADC2 data
– In ADC1: In dual mode, these bits contain the regular data of ADC2. Refer to Section 11.9:
Dual ADC mode
– In ADC2 and ADC3: these bits are not used
Bits 15:0 DATA[15:0] : Regular data
These bits are read only. They contain the conversion result from the regular channels. The
data is left or right-aligned as shown in Figure 30 and Figure 31 .
