Can't make change to the protect bits 2-6 (BP0, BP1, BP2, BP3 and TB) anymore. There is no information on the Status Register Bits 7 in "EPCQ-L Serial Configuration Devices Datasheet"
Basically, Status Register Bits 7 is doing nothing. Thus, it is does not matter either 0 or 1.
Do you able to change the Status Register bits 2-6 before?
Do you make any changes before the protect bits 2-6 can't make change?
Yes, I did changed the protect bit register to 0x48 and some how it read back 0xC8 from the status register. When I try to write to the status register again, the status register read back 0xCA and Flag Status Register read back 0x83 (Failure or protection error).
