Data
The GE_CONFIG command writes the specified data to the specified address. This enables resetting clipping area
and transparent color during command execution.
Argument 1 (Address)
D[31:0] Address[31:0] Bits
Specifies the address of the GE register to be altered.
Argument 2 (Data)
D[31:0] Data[31:0] Bits
Specifies the 32-bit data to be written to the GE register.
Note: The GE_CONFIG command performs a 32-bit writing to the specified address. Therefore, be sure
to specify a word boundary address and a 32-bit writing data.
When the clip area specified by the GE_CONFIG command is beyond the work area, a calcula-
tion error will occur. Clip area size must be equal to or less than that of the work area.
