• So that the display does not break up, make settings such that DMA transfer to the SE buffer is
efficient. Some recommendations follow as examples.
 SEWIDH bits: Set these bits for a number of pixels that is a multiple of eight (320, 480,
and so on).
 Output block DMA transfer size bit: Set this to one (32 bits).
 Amount transferred per operand: Set this to a large value.
 DMAC transfer mode: Select pipeline transfer.
