    Peripheral/GPIO Function
    After reset, the Boot ROM code executes instructions for 1260 SYSCLKOUT cycles (SYSCLKOUT = XCLKIN/2) and then samples BOOT
    Mode pins. Based on the status of the Boot Mode pin, the boot code branches to destination memory or boot code function in ROM. The
    BOOT Mode pins should be held high/low for at least 2520 XCLKIN cycles from boot ROM execution time for proper selection of Boot
    modes.
    If Boot ROM code executes after power-on conditions (in debugger environment), the Boot code execution time is based on the current
    SYSCLKOUT speed. The SYSCLKOUT will be based on user environment and could be with or without PLL enabled.
