8.1
Immediately following power-on, all internal registers as
well as the RAM content are undefined. A RES pulse must
be applied.
Reset is accomplished by applying an external reset pulse
(active LOW) at pin RES. When reset occurs within the
specified time, all internal registers are reset however the
RAM is still undefined. The state after reset is described in
Section 8.2.
RES input must be 0.3V
(or higher) within a maximal time t
HIGH (see Fig.16).
8.2
After reset the LCD driver has the following state:

8.3.1
When PD = 1 the chip is in Power-down mode:
8.3.2
When V = 0, the horizontal addressing is selected. The
data is written into the DDRAM as shown in Fig.6.
When V = 1, the vertical addressing is selected. The data
is written into the DDRAM as shown in Fig.5.
8.3.3
When H = 0 the commands ‘display control’, ‘set
Y-address’, ‘set X-address’ and ‘set the PRS bit’ (LOW or
HIGH range of the high-voltage generator) can be
performed; when H = 1 the others can be executed. The
commands ‘write data’ and ‘function set’ can be executed
in both cases.

The bits D and E select the display mode (see Table 2).
