HS0 to HS2: Set the amount of smooth scrolling to be applied to MDATA in the left/right direction.
VS0 to VS3: Set the amount of smooth scrolling to be applied to MDATA in the up/down direction.
R/L: Specifies the MDATA shift direction (left or right).
Assume that a 32 digits
instruction, and that the following data has been written to DCRAM with the “DCRAM data write” instruction.
Notes: 16: This shift cannot be used when MDATA is 5
