Parameters to different Clock

[guilhermecd]

Greetings, my name is Guilherme.
I am trying to use the RA8875 with an Arduino UNO.
An old screen 480x272, working clock with 25MHz. But I do not know what to do with field the fields below.
When I run with the default settings I have a display half black and half colored vertically.

Thank you very much in advance.

_writeRegister (RA8875_PLLC1 ,?); //// PLL Control Log 1
delay (1);
_writeRegister (RA8875_PLLC2 ,?); //// PLL control record 2
delay (1);
_writeRegister (RA8875_PCSR ,?); // Pixel clock setting log
delay (1);
