3. Software data protetion
To prevent unintentional programming caused by noise generated by external circuits. This device has
the software data protection function. In software data protection mode, 3 bytes of data must be input
before write data as follows. And these bytes can switch the non-protection mode to the protection mode.
SDP is not enabled if only the 3 bytes code is input.

Normal data input
Software data protection mode can be cancelled by inputting the following 6 bytes. After that, this device
turns to the non-protection mode and can write data normally. But when the data is input in the
cancelling cycle, the data cannot be written.
