52 / 138 page  Register Description by Block ADE3800 52/138 DMEAS_MODE_CTRL 0901 R/W [7] 00 DE reset 0*: do not reset the de_mismatch_flag 1: reset the de_mismatch_flag R/W [6] DE freeze 0*: update I2C registers after every measurement in free run mode 1: freeze DE size results in I2C registers and do not update while this bit is active R/W [5] DE one shot 0*: free run mode. 1: one shot mode. Applies only to DE_Size measurement. All other measurements are always in One_shot mode. R/W [3] h_v_pos_sel / pcd_sel - if algorithm = 01 (pcd_sel) 0*: pixel < threshold 1: pixel >= threshold - if algorithm = 10 (h_v_pos_sel) 0*: pixel > threshold (normal) 1: abs (pixel - previous pixel) > threshold R/W [2] DMEAS all clear All internal result registers are cleared when this bit is set. This bit is self clearing. R [1] DMEAS polling bit. Toggles at the end of each measurement in free-run mode. Undefined in one-shot mode. R/W [0] DMEAS start Data measurement start. This bit is auto-cleared by HW when the measurement is completed. DMEAS_THRESHOLD 0902 R/W [7:0] 00 Threshold value to use for selected algorithm. DMEAS_WIN_MIN_X_L DMEAS_WIN_MIN_X_U 0903 0904 R/W R/W [7:0] [3:0] 00 00 Minimum X for window control to use with all algorithms. DMEAS_WIN_MAX_X_L DMEAS_WIN_MAX_X_U 0905 0906 R/W R/W [7:0] [3:0] FF 00 Maximum X for window control to use with all algorithms. DMEAS_WIN_MIN_Y_L DMEAS_WIN_MIN_Y_U 0907 0908 R/W R/W [7:0] [3:0] 00 00 Minimum Y for window control to use with all algorithms. DMEAS_WIN_MAX_Y_L DMEAS_WIN_MAX_Y_U 0909 090A R/W R/W [7:0] [3:0] FF 00 Maximum Y for window control to use with all algorithms. DMEAS_DE_REF_L DMEAS_DE_REF_H 090B 090C R R [7:0] [7:0] 00 00 DE size expected result DMEAS_DE_TOL 090D R [7:0] 00 DE tolerance value Table 21: DMEAS Registers (Sheet 2 of 3) Register Name Addr Mode Bits Rst Description |
