Analog-to-digital converters (ADC) RM0351
592/1830 DocID024597 Rev 5
Bits 31:11 Reserved, must be kept at reset value.
Bit 10 ROVSM: Regular Oversampling mode
This bit is set and cleared by software to select the regular oversampling mode.
0: Continued mode: When injected conversions are triggered, the oversampling is temporary
stopped and continued after the injection sequence (oversampling buffer is maintained during
injected sequence)
1: Resumed mode: When injected conversions are triggered, the current oversampling is aborted
and resumed from start after the injection sequence (oversampling buffer is zeroed by injected
sequence start)
Note: Software is allowed to write this bit only when ADSTART=0 (which ensures that no conversion
is ongoing).
Bit 9 TROVS: Triggered Regular Oversampling
This bit is set and cleared by software to enable triggered oversampling
0: All oversampled conversions for a channel are done consecutively following a trigger
1: Each oversampled conversion for a channel needs a new trigger
Note: Software is allowed to write this bit only when ADSTART=0 (which ensures that no conversion
is ongoing).
Bits 8:5 OVSS[3:0]: Oversampling shift
This bitfield is set and cleared by software to define the right shifting applied to the raw oversampling
result.
0000: No shift
0001: Shift 1-bit
0010: Shift 2-bits
0011: Shift 3-bits
0100: Shift 4-bits
0101: Shift 5-bits
0110: Shift 6-bits
0111: Shift 7-bits
1000: Shift 8-bits
Other codes reserved
Note: Software is allowed to write these bits only when ADSTART=0 (which ensures that no
conversion is ongoing).
