Take precautions when using LOAD4 mode with the DLP650LNIR DMD, or similar DMDs where the number of rows per reset block is not evenly divisible by 4. In the case of the DLP650LNIR, the number of rows per block for this DMD is 50 rows which is not evenly divisible by 4. Therefore, loading the last two rows of an even number block (n = 0,2,4,...14) concurrently loads the first two rows in the subsequent odd number block (n+1). Conversely, to address and load an odd block using LOAD4, the last two rows of the preceding even number block will be loaded first, else the first two rows of the odd block will not be loaded with new data.
