Hi team,

Here's an issue from the customer may need your help:

Unlocking PF0 requires the following three lines, but it is not clear how to write to unlock:

    HWREG(GPIO_PORTF_BASE + GPIO_O_LOCK) = GPIO_LOCK_KEY;

    HWREG(GPIO_PORTF_BASE + GPIO_O_CR) |= 0x01;

    HWREG(GPIO_PORTF_BASE + GPIO_O_LOCK) = 0;

Could you help check this case? Thanks.

Best Regards,

Cherry
