Special Purpose Data Memory

This area of Data Memory is where registers, necessary for the correct operation of the microcontroller,
are stored. Most of the registers are both readable and writeable but some are protected and are readable
only, the details of which are located under the relevant Special Function Register section. Note that for
locations that are unused, any read instruction to these addresses will return the value "00H".
