6.2.11
The normal Display mode on command (NORON) turns the display into Normal mode which is also the reset state.
An explanation of how the command NORON can be used is illustrated in Fig.6.
Table 20 Normal Display mode on register bits
6.2.12
The Display inversion off command (INVOFF) turns the display into a non-inverted screen without modifying the display
data RAM. Display inversion off is the reset state of the PCF8833.
Table 21 Display inversion off register bits
6.2.13
The Display inversion on command (INVON) turns the display into an inverted screen without modifying the display data
RAM. The RAM data is read out and inverted while writing to the display.
The display Inversion mode can be switched off by sending the INVOFF command; see Section 6.2.12.
When sending INVON, in Partial mode only, the pixels of a partial area are inverted. INVON is overruled by DAL and
DALO. In Partial mode the pixels outside of the partial are always off.
Table 22 Display inversion on register bits
6.2.14
The All pixels off command (DALO) can be switched off by sending the normal display on command (NORON) (see
Section 6.2.11) or by sending the partial Display mode on command (PTLON); see Section 6.2.10. Furthermore DALO
is left with the command DAL; see Section 6.2.15. When DALO is active all pixels are driven, as if the display RAM was
filled with all zeros (off-state). DALO does not change the data stored in the display RAM. Figure 6 illustrates how DAL
(all pixels on) and DALO (all pixels off) can be used.
All pixels will be switched off regardless of the display data RAM.
