0 ADEVT_PSEL ADEVT Pin Pull Control Select. This bit selects a pull-down or pull-up on the ADEVT pin if it is
configured to be an input pin.
Any operating mode read/write:
0 Pull-down is selected on ADEVT pin.
1 Pull-up is selected on ADEVT pin.
22.3.51 ADC Event Group Sample Cap Discharge Control Register (ADEVSAMPDISEN)
ADC Event Group Sample Cap Discharge Control Register (ADEVSAMPDISEN) is shown in Figure 22-80
and described in Table 22-57.

15-8 EV_SAMP_DIS_CYC Event Group sample cap discharge cycles. These bits specify the duration in terms of ADCLK
cycles for which the ADC internal sampling capacitor is allowed to discharge before sampling
the input channel voltage.
7-1 Reserved 0 Reads return 0. Writes have no effect.
0 EV_SAMP_DIS_EN Event Group sample cap discharge enable.
Any operation mode read/write:
0 Event Group sample cap discharge mode is disabled.
1 Event Group sample cap discharge mode is enabled. The ADC internal sampling capacitor is
connected to the V
REFLO
reference voltage for a duration specified by the EV_SAMP_DIS_CYC
field. After this discharge time has expired the selected ADC input channel is sampled and
converted normally based on the Event Group settings.
