Description

ADC sample time register 2

Fields

SMP10

Channel x sampling time selection (x = 0 to 9) These bits are written by software to select the sampling time individually for each channel. During sampling cycles, the channel selection bits must remain unchanged. Note: The software is allowed to write these bits only when ADSTART = 0 and JADSTART = 0 (which ensures that no conversion is ongoing).

0 (B_0x0): 5 ADC clock cycles

1 (B_0x1): 6 ADC clock cycles

2 (B_0x2): 12 ADC clock cycles

3 (B_0x3): 20 ADC clock cycles

4 (B_0x4): 36 ADC clock cycles

5 (B_0x5): 68 ADC clock cycles

6 (B_0x6): 391 ADC clock cycles

7 (B_0x7): 814 ADC clock cycles
