GSPMD [0:2]
74 to 76
I
Mode selection signals [0 to 2] for the gray-scale mode. The setting process for the mode selection lines
is described below. GSPMD0 is the LSB and GSPMD2 is the MSB.
IOMD [0:1]
2, 3
I
Input/output mode select pins. The input/output mode selection lines are described below. IOMD0 is the
LSB and IOMD1 is the MSB.
VMD
77
I
Gray-scale processing algorithm select pin. The LC11011-141 algorithm is selected when high. Normal
mode is selected when low or open.
SCLK
81
I
Clock signal input. Data is processed according to this clock signal.
DSIFT
143
I
In input/output mode 1, data is shifted out on both
×
D0 and
×
D1 when high.
Do not use gray-scale modes 0 to 3 with TFT LCD modules that perform FRC or other inter-frame
processing.
