Read Status Operation
The read status operation code is
b'0000 0101
, with the MSB listed first.
You can use the read status operation to read the status register.
Figures 4–7
and
4–8
show the status bits in the status register of both
serial configuration devices.

Figure 4–8. EPCS1 Status Register Status Bits
Setting the write in progress bit to 1 indicates that the serial configuration
device is busy with a write or erase cycle. Resetting the write in progress
bit to 0 means no write or erase cycle is in progress.
Resetting the write enable latch bit to
0
indicates that no write or erase
cycle will be accepted. Set the write enable latch bit to
1
before every write
bytes, write status, erase bulk, and erase sector operation.
The non-volatile block protect bits determine the area of the memory
protected from being written or erased unintentionally.
Tables 4–9
and
4–10
show the protected area in both serial configuration devices with
reference to the block protect bits. The erase bulk operation is only
