CC2340R5: HFXT load capacitance

Hi,

I'm not sure if it is documented, but I've used this code snippet previously:

static void AdjustLoadCap(void)
{
    // Q1 and Q2 values are 6 bits. it has been mentioned before that Q1 should be set same as Q2.
    const uint8_t Val_Q1 = loadCAP_VAL;
    const uint8_t Val_Q2 = loadCAP_VAL;

    // clear previous trims for Q1 and Q2
    HWREG(CKMD_BASE + CKMD_O_HFXTTARG) &= ~(CKMD_HFXTTARG_Q1CAP_M |
                                              CKMD_HFXTTARG_Q2CAP_M);

    // set values for Q1 and Q2
    HWREG(CKMD_BASE + CKMD_O_HFXTTARG) |=
            ((Val_Q1 << CKMD_HFXTTARG_Q1CAP_S) & CKMD_HFXTTARG_Q1CAP_M) |
            ((Val_Q2 << CKMD_HFXTTARG_Q2CAP_S) & CKMD_HFXTTARG_Q2CAP_M);

    // enable the HFXO
    HWREG(CKMD_BASE + CKMD_O_HFXTCTL) |= CKMD_HFXTCTL_EN;

    // wait for the HFXO to be ready
    while ( (HWREG(CKMD_BASE + CKMD_O_AMPSTAT) & CKMD_AMPSTAT_STATE_M)
            !=
            CKMD_AMPSTAT_STATE_SETTLED);

    // Enable tracking loop with HFXT as reference. This will automatically
    // calibrate LFOSC against HFXT whenever HFXT is enabled; usually after
    // waking up from standby.
    // This is needed to ensure fast HFXT startup and a reasonably accurate
    // LFOSC frequency.
    HWREG(CKMD_BASE + CKMD_O_HFTRACKCTL) |= CKMD_HFTRACKCTL_EN_M | CKMD_HFTRACKCTL_REFCLK_HFXT;

}

Thanks,
