Set X address
The X address points to the columns. The range of X is
0 to 100 (64H).
Reset function
After power-on the chip has the following state:
Power-down mode (PD = 1)
RAM undefined
RAM X and Y address undefined
Display control bits (except PD) undefined
I
2
C-bus interface reset.
Note
If the chip is used with an external clock source, after
power-on, the chip requires at least 2 clock pulses to
ensure that an internal synchronous reset is carried out.
After the internal reset, the chip goes into power-down
mode (PD = 1). If the clock pulses are not supplied, and
the reset is not cleared, the chip cannot respond to
commands in the I
2
C bus.
In applications where the internal oscillator is used
(pin OSC = V
DD
), the oscillator starts after power-on.
As soon as the synchronous reset is cleared, the chip goes
into power-down mode, and the oscillator is stopped.
