Serial Configuration Device Memory Access
available when all the block protect bits are
0
. When any of the block
protect bits are set to one, the relevant area is protected from being
written by write bytes operations or erased by erase sector operations.
The status register can be read at any time, even while a write or erase
cycle is in progress. When one of these cycles is in progress, you can check
the write in progress bit (bit
0
of the status register) before sending a new
operation to the device. The device can also read the status register
continuously, as shown in
Figure 4–9
.
