Bit 4 is clock-enable bit. This bit sets to 1, the
signal CO,CL1,FLM and M stop in master mode.
They are high-Z. Data bits 7 and 5 are unused;
they should be set to 0 when written to.
Gray Scale Palette Registers (R12 to R15):
The
gray scale palette registers (figure 43) designate
the grayscale level or colour. Use these registers
to enable an optimal grayscale or colour display.
If GRAY bit is 1, these registers are inactive. Data
bits 7 to 5 are unused; they should be set to 0
when written to.

Blink Registers (R8 to R10):
The blink bit
registers (figure 41) designate the 8-bit groups to
be blinked. Setting a bit to 1 blinks the correspond-
ing 8-bit group. Any number of groups can be
blinked; setting all the bits to 1 will blink the entire
LCD panel. These bits are valid only when the
BLK bit of control register 2 is 1. R10's data bits 7
to 4 are unused; they should be set to 0 when
written to.
Partial Display Block Register (R11):
The Partial
display block register (figure 42) designates the
block of partial display. It use from bit 3 to bit 0.
