The bits of the protection memory can be addressed directly for reading or programming.
A protection bit address corresponds to the lowest address within the respective page
(A3 to A6 or A7, A0 to A2 = zero). The status of each protection bit is sensed internally.
A written state (
“0”) prevents programming in the associated page. If an already
protected memory page is accidentally addressed for programming, the programming
procedure is suppressed.
The conventional
I
2
C-Bus protocol allows data bytes to be read and programmed only.
Therefore an independent instruction sequence for addressing and manipulation of
protection bits is implemented. For protection bit instructions, the command byte CSW
with its preceding START condition followed by the associated control byte has to be
entered twice (
figures 15
through
17
). The first command byte CSW is followed by the
control byte EEA with the bit/page address A0 through A2 always at zero. The second
CSW is required for entering a control byte CTx for protection bit manipulation. The three
control bytes for read, write or erase of a protection bit are listed below (
table 3
):
