Used when OokThresType = 00 RegAfcFei (0x1E) 7 - r 0 unused 6 FeiDone r 0 0 → FEI is on-going 1 → FEI finished 5 FeiStart w 0 Triggers a FEI measurement when set. Always reads 0. 4 AfcDone r 1 0 → AFC is on-going 1 → AFC has finished 3 AfcAutoclearOn rw 0 Only valid if AfcAutoOn is set 0 → AFC register is not cleared before a new AFC phase 1 → AFC register is cleared before a new AFC phase 2 AfcAutoOn rw 0 0 → AFC is performed each time AfcStart is set 1 → AFC is performed each time Rx mode is entered 1 AfcClear w 0 Clears the AfcValue if set in Rx mode. Always reads 0 0 AfcStart w 0 Triggers an AFC when set. Always reads 0.
