P/E/R Controller and Cache Ready/Busy Bit (SR6)
Status Register bit SR6 has two different functions depending on the current operation.
During Cache Read operations SR6 acts as a Cache Ready/Busy bit, which indicates
whether the Cache Register is ready to accept new data. When SR6 is set to '0', the Cache
Register is busy and when SR6 is set to '1', the Cache Register is ready to accept new data.
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; when the
bit is set to ‘1’, the P/E/R Controller is inactive.
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.
