38 / 138 page  Register Description by Block ADE3800 38/138 Note: Timeout and Tolerance use Horizontal and Vertical measurements. These can either be the Horizontal or Vertical syncs from an Analog input or the local generated Horizontal Enable and/or Vertical Enable. Table 17: SMEAS Register Definitions (Sheet 1 of 6) Register Name Addr Mode Bits Rst Description SMEAS_ACT_CTRL 0100 R/W [3] 00 Free-run enable R/W [2] Freeze results during free run mode. No meaning in one shot mode. 0*: Do not freeze. New result will be available on the next and subsequent toggle of the polling bit. 1: Freeze the current results. The polling bit will still toggle and the block continues to free run; however, results will not update. R/W [1] Activity detection start. In one-shot mode setting this bit triggers the start of a measurement. This bit is reset to zero when the measurement is complete. No meaning in free run mode. R/W [0] Activity detection mode. 0*: free-run mode 1: one-shot mode SMEAS_ACT_H_SMPTM_L SMEAS_ACT_H_SMPTM_U 0101 0102 R/W R/W [7:0] [7:0] 00 00 Sample period value for clock or HSync activity. Xclks [7:0] Sample period value for clock or HSync activity. Xclks [15:8] SMEAS_ACT_V_SMPTM_L SMEAS_ACT_V_SMPTM_U 0103 0104 R/W R/W [7:0] [7:0] 00 00 Sample period value for vsync activity. Xclks / 256 [7:0] Sample period value for vsync activity. Xclks / 256 [15:8] SMEAS_ACT_H_MINEDGE 0105 R/W [7:0] 00 Minimum edge count value for clk or HSync activity. SMEAS_ACT_V_MINEDGE 0106 R/W [7:0] 00 Minimum edge count value for vsync activity. SMEAS_H_TMOT_L SMEAS_H_TMOT_U 0107 0108 R/W R/W [7:0] [7:0] 00 00 Timeout counter value for clk or horizontal measurement. xclks [7:0] Timeout counter value for clk or horizontal measurement. xclks [15:8] SMEAS_V_TMOT_L SMEAS_V_TMOT_U 0109 010A R/W R/W [7:0] [7:0] 00 00 Timeout counter value for vertical measurement. xclks / 256 [7:0] Timeout counter value for vertical measurement. xclks / 256 [15:8] SMEAS_CLEAR 0110 R/W [1] 00 clears SMEAS_STATUS_RANGE[7] sticky bit only. Must be reset by software. [0] clears timeouts, measurements. Must be reset by software. |
