WPSEL:
    When WPSEL is Enabled, the Block Protection Mode bits (SRWD and bp[3-0]) no longer preform any function and become read only.
    The Block Protection Bits[3-0] (bits 5-2 of the Status Register) will be permanently set to a value of 1.
    The Status Register Write Protect Bit (bit 7 of the Status Register) will be permanently set to it's current value.

Sector Protection Mode:
    An SPB register is assigned to each 4KB sector in the bottom and top 64KB of memory and to each 64KB block in the remaining memory.
    Setting the SPB register of a sector/block to 0xFF will protect the data in that sector/block from modification.
    This device has 158 SPB registers, indexed 0 - 157

    To set a single SPB register, enter its index
    Example: To set SPB at index 13, enter 13

    To set a range of SPB registers, separate the low and high register indexes with a hyphen
    Example: To set SPBs at indexes 3 - 17, enter 3-17

    To specify multiple indexes or ranges, separate the indexes or ranges with a comma
    Example: To set SPB at indexes 13, 22-27, 31-40 and 47, enter 13,22-27,31-40,47
