I can't turn on CFAF320240,:(

[Jose83]

Hi tried to turn on the CFAF320240, my configuration is a SPI interface, and i use only the SPI pins. My pins used are:

RS
RW
SDO
CS
SCL
SDA
RESET

I found in the datasheet CFAF320240 pag. 13, an a sequence but use the DOTCLOCK,HSYNC,and VSYNC. My question is, is necessary use the DOTCLOCK,HSYNC,and VSYNC, to turn on the TFT module?.

Additional info, i have to migrate to app. note from avr to dspic33, please im not sure what's the ploblem.

If it is an LED backlight, please remember you need to limit the current in the LEDs, or they will fail.
