While RST_ACTIVE is high, and for 8 μs after, the data for the block(s) being issued a Mirror Clocking Pulse should not be changed to allow for the settling required for the mirrors to become stable. It is possible to load other blocks while the block previously issued a Mirror Clocking Pulse is settling. Figure 13 shows a single block load, Mirror Clocking Pulse and reload sequence with the light gray areas indicating mirror settling time. It is best to issue a float command to avoid leaving a static image on the DMD for extended periods of time. A mirror float sequence begins by asserting the proper BLK_MD and BLK_AD as described in Table 9. During the following row cycle, the DMD releases the tension under each mirror so that all mirrors are in a relatively flat position. The float operation takes approximately 3 μs to complete, during which time RST_ACTIVE is asserted.
