Protection Bit Write and Erase
For writing or erasing a protection bit, the data of the respective page have to be known
by the master. The data of the page are not affected by the write or erase procedure of
the protection bit. The I
2C-Busprotocolisshown in figure 15 for protection bit write and
figure 16 for protection bit erase.
Figure 15
Sequence for Protection Bit Write
Figure 16
Sequence for Protection Bit Erase
The first command byte CSW followed by the control byte EEA addresses the page to
be protected. The second command byte CSW (identical content of first CSW) is
followed by the control byte CTW = 01
H for protection bit write or CTE = 03H for protection
bit erase. Depending on CTx, the addressed protection bit will be either written or
erased.
