P/E/R Controller
Status Register bit SR6 has two different functions depending on the current operation.
During all other operations 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).
P/E/R Controller Bit (SR5)
The Program/Erase/Read Controller bit 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 is used to identify 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 opera-
tion has completed successfully.
SR4, SR3 and SR2 are Reserved
