Description
This command is used to define area of frame memory where MCU can access. This command makes no change on the
other driver status. The values of SC [15:0] and EC [15:0] are referred when RAMWR command comes. Each value
represents one column line in the Frame Memory.
SC[15:0] EC[15:0]
X = Don’t care
Restriction
SC [15:0] always must be equal to or less than EC [15:0].
Note 1: When SC [15:0] or EC [15:0] is greater than 00EFh (When MADCTL’s B5 = 0) or 013Fh
(When MADCTL’s B5 = 1), data of out of range will be ignored
