49.4.3.2 Blink frequency
The LCD clock is the basis for the calculation of the LCD controller blink frequency. The
LCD controller blink frequency is equal to the LCD clock (LCLK) divided by the factor
selected by the BRATE[2:0] bits. The following table shows LCD controller blink
frequency calculations for all values of BRATE[2:0] at a few common LCLK selections.
49.4.4 LCD charge pump and power supply operation
This section describes the LCD charge pump and LCD power supply configuration
options.
The LCD bias voltages (V

source to the LCD charge pump is controlled by the VSUPPLY[1:0] bit field.

and lower nibble. For Example, if LCD_P0 is configured as backplane 0 (phase A) then for proper operation in Alternate
Display mode, the WF3to0 should be set to 0x00000011 to set both BPEWF0 and BPAWF0.
