Unable to Set 9S08GW Pins With LCD to output only

[Designer11]

Hi All,

I'm having an issue trying to configure the pins PTD, and PTE to operate in output mode only. For a test, i tried to toggle PTD4 and PTD5 from low to high and vice versa. Below is a snippet of my code. I had VLL3 connected to VDD (3.3V), but no luck at all.

SOPT1 = 0b11011010;

//clock setting

ICSC1 = 0x06;

ICSC2 = 0x00;

ICSTRM = 0x8B;

ICSSC = 0x20;

    /** Enable clock to the LCD module */

    SCGC2_LCD = 1;

    /** Disable LCD module */

    LCDC0_LCDEN = 0;

    LCDC1_FCDEN = 1;

    LCDSUPPLY_VSUPPLY = 0b11

///Toggle pins direction

    PTDDD_PTDDD4    = 0x01;

    PTDDD_PTDDD5  = 0x01;

    //Switches input controls

    PTDD_PTDD4 = 0x01;

    PTDD_PTDD5 = 0x00;

I've looked at the below post, but it doesn't help much.

Re: Ports PTB3, PTB4 and PTB5 on MC9S08GW, Open drain function only?

Thank you in advance for any help that can be provided!

Hi All,

Problem solved ! First time working with the GW series. I forgot to enable Port D clock via SCGC3 register, SCGC3_PTD = 1.

Thanks.

Hi Vu

yes, I also send you a sample code on the case that you create.
