Erase/Program Suspend Status (SUS)
The Suspend Status bit (SUS) is a read only bit in the status register (S15) that is set to 1 after executing an
Erase/Program Suspend (75h) command. The SUS status bit is cleared to 0 by Erase/Program Resume (7Ah)
command as well as a power down, power-up cycle.
1. X = Don’t care
2. L = Lower; U = Upper
3. If any Erase or Program command specifies a memory region that contains protected data portion, this command is ignored.
4. Note 3 does not apply to this Status Register Bit setting. See Errata 1 at the end of this document for details.
