66 / 109 page  NVM register name Definition Notes Description #Bits Code N_NOTSTART 1 0x0 N_NOTSTART_VAL Self-start rotation speed threshold 0x1 4000 RPM N_NOTSTART_VAL 6 Speed mapping rule: 255-code*4 → Alternator speed measure table (see Section A.13 Alternator speed measure).For example: default code value = 0xC → 255-code*4 = 207 which correspond to 3000RPM into the “Alternator speed measure table”. Default value: 0x0C. Emergency start speed threshold value DREHFILT_MODE 1 0x0 enable Enable/disable PRG_EVENTFILT_2_0 and PRG_EVENTFILT_5_3 0x1 disable PRG_EVENTFILT_2_0 3 0x0 1 Filter number phase periods for detection: LRC and emergency start speed threshold 0x1 3 0x2 5 0x3 7 0x4 9 0x5 11 0x6 13 0x7 15 N0_FILTERTIME_SET 2 0x0 0 ms Filter time before start speed event removal (RPM<Nstart) 0x1 50 ms 0x2 100 ms 0x3 300 ms PRG_EVENTFILT_5_3 3 0x0 0 Number of phase periods for detection before hot start speed event generation 0x1 1 0x2 2 0x3 3 0x4 4 0x5 5 0x6 6 0x7 7 PHASE_FILT_EN 1 0x0 disable Enable first order LPF for phase ADC 0x1 enable KLV_HED_DIS 1 0x0 peak to peak AC threshold Phase regulation option to set which thresholds are applied on PH signal - KLV_HED_DIS = 0: high and low thresholds are considered - KLV_HED_DIS = 1: high threshold only is considered 0x1 peak only AC threshold ACADAPMIN_MODE 1 0x0 AC_ADAP_M_BAND value when normal start, KLV_AC_ADAP_MIN_NOT value when emergency start Adaptive PH threshold lower saturation value for normal/self-start L9918 NVM parameters table DS13000 - Rev 2 page 66/109 |
