5. Disabling Software Protection
Software data protection mode can be disabled by inputting the following data sequence. Once the software pro-
tection sequence has been written, no data can be written to the memory until the write cycle (T
WC
) has elapsed.
Software Protection Disable Sequence
Devices are shipped in the “unprotected” state, meaning that the contents of the memory can be changed as required
by the user. After the software data protection is enabled, the device enters the Protect Mode where no further write
commands have any effect on the memory contents.
