ZHCSE90D September 2015 – September 2020 DLPC910
To avoid leaving a static image on the DMD without removing power, a mirror FLOAT operation can be issued to the DMD. A mirror FLOAT sequence begins by asserting the proper BLKMD and BLKAD as described in Table 7-12. 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 500 μs to complete, during which time RST_ACTIVE is NOT asserted. Normal operation may then continue without resetting or cycling power to the DLPC910 or the DMD.
