PRINCIPLES OF OPERATION
gray scale data
Using this packet, the same gray-scale data can be written to all the connected devices simultaneously or
different gray-scale data can be written to each device.
The constant-current output is turned on (constant-current flows), except that gray-scale data entered to
gray-scale data latch is 0, synchronizing with the next rising edge of the gray-scale clock after the rising edge
of the gray-scale clock with the time delay of t_su from the edge of DTIN/STIN of HSYNC packet LSB. Thereafter,
the 10-bit gray-scale counter counts the number of rising edge of the gray-scale clock and outputs is matched
to gray-scale data is turned off (constant-current flow stops).
The user can select either the gray scale clock using GCLK terminal input or the internally generated clock using
DTIN/STIN terminal input. (See DSG function section for more detail)
