Figure 9 shows a scroll operation in vertical direction (5 steps). No blank column or row is

inserted and wait time is disabled. As for horizontal direction, the only difference is the

number of scroll steps (24 instead of 5). EOSCR bit is set to 1 in the 24th step.

Figure 9. Basic scroll operation

Figure 10 shows a scroll operation with blank row/column insertion enabled. S is the

number of standard scroll steps (with blank row/column insertion disabled). S = 24 for

horizontal direction and 5 in case of vertical direction, n is the number of blank

rows/columns to be inserted.
