SR.3 MUST be cleared, if set during a block erase attempt,
before further attempts are allowed by the Write State

SR.5 is only cleared by the Clear Status Register
Command, in cases where multiple blocks are erased
before full status is checked.
If error is detected, clear the Status Register before
attempting retry or other error recovery.
