To read the contents of the WPR, a random read operation must be sent to the device (see
Random
Read) so that the reserved word address bits A7 and A6 can properly be set.
It is not possible to read the contents of the WPR with a current address read.
When reading the WPR contents, data bit 7 through 4 will always read as a logic
‘0’ as seen in Table 8-4.Figure 8-3. Read Write Protection
Register
Note:
For the AT24CSW04X, the @ indicates the A1
address bit which is managed by the ordering code of the device (see
Table 6-3). For the AT24CSW08X, the
@ indicates the A9 address bit.
# indicates the hardware
address value which is managed by the ordering code of the device (see Table 6-3 and Table 6-4).
