51.6.10 Sample-and-Hold Modes

The AFE can be configured in either single Sample-and-Hold mode (AFEC_SHMR.DUALx = 0) or dual Sample-and-Hold mode (AFEC_SHMR.DUALx = 1). By default, after a reset, the AFE is in single Sample-and-Hold mode.

The AFEC can apply a different mode on each channel.

The same inputs are used in single Sample-and-Hold mode or in dual Sample-and-Hold mode. Single-ended/Differential mode and single/dual Sample-and-Hold mode can be combined. See the following tables.
