Detailed Description

DPM (Detection of Plunger Movement) algorithm configuration.

Maps to the CFG_DPM register (0x0A). Settings are global and apply to all channels that have DPM_EN set. See datasheet "Detection of Plunger Movement Register Description (CFG_DPM)".

• plunger_movement_start_current: Starting current for DPM (0-127). ISTART = value × (IFS/127).
• plunger_movement_debounce_time: Debounce in chopping periods (0-15). TDEB = value / fCHOP.
• plunger_movement_current_threshold: Current dip threshold (0-15). IPTH = value × (IFS/127).
