Flag Status Register
The Flag Status Register is a powerful tool to investigate the status of the device, checking
information regarding what is actually doing the memory and detecting possible error
conditions.
The Flag status register is composed by 8 bit.Three bits (Program/Erase Controller bit,
Erase Suspend bit and Program Suspend bit) are a “Status Indicator bit”, they are set and
reset automatically by the memory. Four bits (Erase error bit, Program error bit, VPP 1 to 0
error bit and Protection error bit) are “Error Indicators bits”, they are set by the memory
when some program or erase operation fails or the user tries to perform a forbidden
operation. The user can clear the Error Indicators bits by mean of the Clear Flag Status
Register (CLFSR) instruction.
All the Flag Status Register bits can be read by mean of the Read Status Register (RFSR)
instruction.
