Setting the write protection
The Write Control (WC) is tied low, hence the write protection of the memory array is
dependent on whether software write-protection has been set.
Software write-protection allows the bottom half of the memory area (addresses 00h to 7Fh)
to be write protected irrespective of subsequent states of the write control (WC) signal.
Software write-protection is handled by three instructions:
●
●
●
The level of write-protection (set or cleared) that has been defined using these instructions,
remains defined even after a power cycle.
