Description
Set gray scale mode and register.
These are two-byte commands used to
specify the contrast levels for the gray
scale, 4 levels available.
After power on reset,
WA0~3 = WB0~3 = WC0~3 = WD0~3 =
0000
LA0~3 = LB0~3 = LC0~3 = LD0~3 =
0000
DA0~3 = DB0~3 = DC0~3 = DD0~3 =
1111
BA0~3 = BB0~3 = BC0~3 = BD0~3 =
1111
Sets PWM and FRC for gray-scale
operation.
FRC = 0 : 4-frame (POR)
FRC = 1 : 3-frame
PWM1 PWM0 = 00 & 01 : 9-levels
(POR)
PWM1 PWM0 = 10 : 12-levels
PWM1 PWM0 = 11 : 15-levels
S0=0: column address 00H is mapped
to SEG0 (POR)
S0=1: column address 7FH is mapped
to SEG0
C0=0: Disable icon row (Mux = 16 to
80, POR)
C0=1: Enable icon row (Mux = 17 to 81)
E0=0: Normal display (display
according to RAM contents, POR)
E0=1: All pixels are ON regardless of
the RAM contents
*Note: This command will override the
effect of “Set Normal/Inverse Display”
R0=0: Normal display (display
according to RAM contents, POR)
R0=1: Inverse display (ON and OFF
