LCD Type MCU

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 writable but some are pro-

tected and are read-only, the details of which are located under the relevant Special Function Reg-

ister section. Note that for locations that are unused, any read instruction to these addresses will

return the value

Â²00HÂ².
