The Idle mode off (IDMOFF) command turns off the Idle mode and the PCF8833 is working in the 4 kbyte colour mode.
This command is similar to the Idle mode on command (IDMON); see Section 6.2.29.
Table 42 Idle mode off register bits
6.2.29
The Idle mode on (IDMON) command activates the Idle mode of the LCD driver in order to reduce the power
consumption. When the Idle mode is switched on, the number of colours is reduced to 8 (only the MSB of data stored in
the RAM is used). In addition to the reduction in the number of colours, the frame frequency can also be reduced. The
frame frequency for the Idle mode can be programmed separately from the frame frequency in 4 kbyte colour mode; see
Section 6.2.41.
Table 43 Idle mode on register bits
6.2.30
By using the Colour interface pixel format command (COLMOD) different interface RGB formats can be chosen. The
choice of an RGB format also influences the way display data is transferred to the display data RAM via the interface;
see Section 7.1.3.
The different interface RGB formats are given in Table 45.
