C6678 PASS PLL (unused)

Hi KazuKon,

I would recommend you to refer the attached gel file of C6678 (1440.evmc6678l.gel )in which the function, "hotmenu getPaPllConfig()" is used to find whether the

PACLKSEL  is set or not. As well as whether the PA PLL is in bypass mode or in PLL mode.

The following is the code snippet from the gel file.

/* Print the current PA PLL configuration */
hotmenu getPaPllConfig()
{
    unsigned int passclksel = (DEVSTAT & PASSCLKSEL_MASK);
    unsigned int papllctl0val = PAPLLCTL0;
    unsigned int papllbypass;
    unsigned int papllod;
    unsigned int papllclkf;
    unsigned int papllclkr;
    unsigned int paplloutput; 

    /* Tells the configuration of the PASSCLKSEL pin */
    if (passclksel == PASSCLKSEL_MASK)  GEL_TextOut("PA PLL is using PASS_CLK as the input\n");
    else  GEL_TextOut("PA PLL is using SYSCLK/ALTCORECLK as the input\n");

    /* Tells whether the PA PLL is in BYPASS mode or not */
    papllbypass = (papllctl0val & PA_PLL_BYPASS_MASK);
    if (papllbypass == PA_PLL_BYPASS_MASK) GEL_TextOut("PA PLL is in bypass mode\n");
    else GEL_TextOut("PA PLL is in PLL mode\n");

In addtion to this, please have a look at other configuration functions of PLL which will be useful and give more clarity to you.
