Analog-to-digital converters (ADC) RM0351
590/1830 DocID024597 Rev 5
Bits 9:6 EXTSEL[3:0]: External trigger selection for regular group
These bits select the external event used to trigger the start of conversion of a regular group:
0000: Event 0
0001: Event 1
0010: Event 2
0011: Event 3
0100: Event 4
0101: Event 5
0110: Event 6
0111: Event 7
...
1111: Event 15
Note: Software is allowed to write these bits only when ADSTART=0 (which ensures that no regular
conversion is ongoing).
Bit 5 ALIGN: Data alignment
This bit is set and cleared by software to select right or left alignment. Refer to Section : Data
register, data alignment and offset (ADC_DR, OFFSETy, OFFSETy_CH, ALIGN)
0: Right alignment
1: Left alignment
Note: Software is allowed to write this bit only when ADSTART=0 and JADSTART=0 (which ensures
that no conversion is ongoing).
Bits 4:3 RES[1:0]: Data resolution
These bits are written by software to select the resolution of the conversion.
00: 12-bit
01: 10-bit
10: 8-bit
11: 6-bit
Note: Software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which
ensures that no conversion is ongoing).
