RM0367 Rev 7 347/1043
RM0367 Analog-to-digital converter (ADC)
352
14.12.6 ADC sampling time register (ADC_SMPR)
Address offset: 0x14
Reset value: 0x0000 0000
Bits 4:2 OVSR[2:0]: Oversampling ratio
This bit filed defines the number of oversampling ratio.
000: 2x
001: 4x
010: 8x
011: 16x
100: 32x
101: 64x
110: 128x
111: 256x
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bit 1 Reserved, must be kept at reset value.
Bit 0 OVSE: Oversampler Enable
This bit is set and cleared by software.
0: Oversampler disabled
1: Oversampler enabled
Note: Software is allowed to write this bit only when ADSTART = 0 (which ensures that no conversion
is ongoing).

Bits 31:3 Reserved, must be kept at reset value.
Bits 2:0 SMP[2:0]: Sampling time selection
These bits are written by software to select the sampling time that applies to all channels.
000: 1.5 ADC clock cycles
001: 3.5 ADC clock cycles
010: 7.5 ADC clock cycles
011: 12.5 ADC clock cycles

111: 160.5 ADC clock cycles
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
