Program Status setting for S29GL-S

[TeMa_2997106]

Program Status bit, bit4 of Status Register, drives to 1 when Program fails. Is this flag set for any reason?

Is 1 set in Program status bit of Status register even when programming fails due to exceeding 100K of P/E Endurance?

Hi

Program Status bit, bit4 of Status Register, drives to 1 when Program fails. Is this flag set for any reason?

There are several conditions under which this bit gets set. The below points are from the S29GL01GS datasheet - 

• During erase suspend, programming to the suspended sector, will cause program failure and set the Program status bit to 1.

• If the sector is protected (by DYB, PPB, or else), program fails and the bit is set
• 
• During PPB Password protection mode - 

Is 1 set in Program status bit of Status register even when programming fails due to exceeding 100K of P/E Endurance?

Program fail bit can get set to 1 if the program operation cannot be completed due to the sector being worn out by P/E cycles.

Regards.

Thanks.

I will check datasheet again.
