SAMPx[2:0]
Channel x sample time selection
These bits are used to independently select the sampling time for each channel. The channel selection
bit must remain constant during the sampling period.
ADC_SAMPT3.SAMPSEL = 0, the sampling time is set as follows:
000: 1.5 cycles 100: 41.5 cycles
001: 7.5 cycles 101: 55.5 cycles
010: 13.5 cycles 110: 71.5 cycles
011: 28.5 cycles 111: 239.5 cycles
ADC_SAMPT3.SAMPSEL = 1, the sampling time is set as follows:
000: 1.5 cycles 100: 19.5 cycles
001: 2.5 cycles 101: 61.5 cycles
010: 4.5 cycles 110: 181.5 cycles
011: 7.5 cycles 111: 601.5 cycles

OFFSETJCHx[11:0]
Data offset for injected channel x
These bits define the values used to subtract from the original conversion data when the
conversion is injected into the channel. The result of the conversion can be read in the
ADC_JDATx register.
