Write protection bit (SR7)
The write protection bit can identify if the device is protected or not. If the write protection bit
is set to ‘1’ the device is not protected and program or erase operations are allowed. If the
write protection bit is set to ‘0’ the device is protected and program or erase operations are
not allowed.
P/E/R controller bit (SR6)
Status Register bit SR6 acts as a P/E/R controller bit, which indicates whether the P/E/R
controller is active or inactive. When the P/E/R controller bit is set to ‘0’, the P/E/R controller
is active (device is busy); when the bit is set to ‘1’, the P/E/R controller is inactive (device is
ready).
Error bit (SR0)
The error bit identifyies if any errors have been detected by the P/E/R controller. The error bit
is set to ‘1’ when a program or erase operation has failed to write the correct data to the
memory. If the error bit is set to ‘0’, the operation has completed successfully.
Read electronic signature
The device contains a manufacturer code and device code. The following three steps are
required to read these codes:
1.

Device identifier codes
Electronic signature
(1)
One bus write cycle to issue the Read Electronic Signature command (90h)
One bus write cycle to input the address (00h)
Four bus read cycles to sequentially output the data (as shown in
signature).
