20 / 32 page  MT9P031 www.onsemi.com 20 Table 13. OPERATING MODE (continued) Mode Description Settings GRR Snapshot Snapshot = 1; Global_Reset = 1 Frames are output one at a time, with each frame initiated by a trigger. GRR is used. Readout is electronically triggered based on SW. GRR Bulb Snapshot = 1; Bulb_Exposure = 1; Global_Reset = 1 Frames are output one at a time, with each frame initiated by a trigger. GRR is used. Readout is initiated by a second trigger. 1. In ERS bulb mode, SW must be greater than 4 (use trigger wider than tROW * 4). All operating modes share a common set of operations: 1. Wait for the first trigger, then start the exposure. 2. Wait for the second trigger, then start the readout. The first trigger is by default automatic, producing continuous images. If snapshot is set, the first trigger can either be a low level on the TRIGGER pin or writing a “1” to the trigger register field. If Invert_Trigger is set, the first trigger is a high level on TRIGGER pin (or a “1” written to trigger register field). Because TRIGGER is level-sensitive, multiple frames can be output (with a frame rate of tFRAME) by holding TRIGGER pin at the triggering level. The second trigger is also normally automatic, and generally occurs SW row times after the exposure is started. If Bulb_Exposure is set, the second trigger can either be a high level on TRIGGER or a write to Restart. If Invert_Trigger is set, the second trigger is a low level on TRIGGER (or a Restart). In bulb modes, the minimum possible exposure time depends on the mechanical shutter used. After one frame has been output, the chip will reset step 1, above, eventually waiting for the first trigger again. The next trigger may be issued after ((VB - 8) x tROW) in ERS modes or tALLREST in GRR modes. The choice of shutter type is made by Global_Reset. If it is set, the GRR shutter is used; otherwise, ERS is used. The two shutters are described in “Electronic Rolling Shutter” and “Global Reset Release”. The default ERS continuous mode is shown in Figure 8. Figure 23 shows default signal timing for ERS snapshot modes, while Figure 24 shows default signal timing for GRR snapshot modes. Figure 23.
