6.7.3
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).
6.7.4
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 operation has completed successfully.
