Read Flag Status Register
The Read Flag Status Register (RFSR) instruction allows the Flag Status Register to be
read. The Status Register may be read at any time, even while a Program, Erase. When one
of these cycles is in progress, it is recommended to check the P/E Controller bit (Not WIP)
bit before sending a new instruction to the device. It is also possible to read the Flag
Register continuously, as shown here.

Clear Flag Status Register
The Clear Flag Status Register (CLFSR) instruction reset the error Flag Status Register bits
(Erase Error bit, Program Error bit, VPP Error bit, Protection Error bit). It is not necessary to
set the WEL bit before the Clear Flag Status Register instruction is executed. The WEL bit
will be unchanged after this command is executed.
