68 / 76 page  DA7280 LRA/ERM Haptic Driver with Multiple Input Triggers, Integrated Waveform Memory and Wideband Support Datasheet Revision 3.0 30-Jul-2019 CFR0011-120-00 68 of 76 © 2019 Dialog Semiconductor Table 64: FRQ_LRA_PER_ACT_L (0x0047) Bit Mode Symbol Description Reset [6:0] RO LRA_PER_ACTUAL _L LSBs of the actual LRA resonant period based on half-period, see Section 5.5.The following formula describes the output: ������������ ������������������������ (��������) = 1333.32 × 10−9 × (128 × ������������_������������_������������������������_���� + ������������_������������_������������������������_����) 0x4F Table 65: FRQ_PHASE_H (0x0048) Bit Mode Symbol Description Reset [7:0] RW DELAY_H Used during custom waveform operation, see Section 5.7.5. Only use the following settings, all other settings are reserved: 0x0 = Setting for wideband mode 0x25 = Setting for closed-loop frequency tracking mode 0x25 Table 66: FRQ_PHASE_L (0x0049) Bit Mode Symbol Description Reset [7] RW DELAY_FREEZE Used during custom waveform operation. Set to 1 only in wideband mode with frequency tracking disabled, see Section 5.7.5 0x0 = Setting for closed-loop frequency tracking mode 0x1 = Setting for wideband mode 0x0 [2:0] RW DELAY_SHIFT_L Used during custom waveform operation, see Section 5.7.5. Only use the following settings, all other settings are reserved: 0x0 = Setting for wideband mode 0x5 = Setting for closed-loop frequency tracking mode 0x5 Table 67: FRQ_CTL (0x004C) Bit Mode Symbol Description Reset [1] RW FREQ_TRACKING_ AUTO_ADJ Enables the auto-scaling of the frequency tracking proportional coefficient, see Section 5.7.1. 0x0 = No auto-scaling 0x1 = Auto-scaling 0x1 [0] RW FREQ_TRACKING_ FORCE_ON Force the tracking on when the error exceeds 25 % of initial guess, see Section 5.7.1. 0x0 = Off 0x1 = On 0x0 Table 68: TRIM3 (0x005F) Bit Mode Symbol Description Reset [6] RW LOOP_IDAC_DOU BLE_RANGE Loop IDAC double range control, see Section 5.7.12 0x0 [5] RW LOOP_FILT_LOW_ BW Loop filter low bandwidth, see Section 5.7.9 0x0 |
