MC9S08LL16 GPIO shareed with LCD pins problem

[VincentLau]

Hi, I am using MC9s08LL16. I find PTD and PTE which are shared with LCD pins only output 3V. However I have disable the LCD module as I only use them as GPIO to output 3.3V logic level. Here is the codes:

  LCDSUPPLY_CPSEL = 1;
  LCDSUPPLY_LADJ = 0;
  LCDSUPPLY_BBYPASS = 0;
  LCDSUPPLY_VSUPPLY1 = 0;
  LCDSUPPLY_VSUPPLY0 = 1;
 
  LCDC0_LCDEN = 0;  
  LCDC1_FCDEN = 1;
  LCDRVC_RVEN = 0;

Can anyone helps me? Thanks a lot!
