Dear Elfred,

the easiest way to check MCU-S1D13705 interface would be rading chip ID
(offset 0x00 in registers area). Then you can try to drive GPIO pins
(also using control register). If those work then there is nothing else
left but setting properly LCD interface registers and see if your
display works (you may also do it without LCD by probing S1D13705
display driving signals on the oscilloscope ie.FPFRAME). When attaching
LCD remember to set up look-up table (LUT) so you can display colors or
gray shades.

Have fun

Wlad
