9.1.6
Complement Protect (CMP)
The Complement Protect bit (CMP) is a non-volatile read/write bit in the status register (S14). It is used in
conjunction with SEC, TB, BP2, BP1 and BP0 bits to provide more flexibility for the array protection. Once
CMP is set to 1, previous array protection set by SEC, TB, BP2, BP1 and BP0 will be reversed. For
instance, when CMP=0, a top 4KB sector can be protected while the rest of the array is not; when
CMP=1, the top 4KB sector will become unprotected while the rest of the array become read-only. Please
refer to the Status Register Memory Protection table for details. The default setting is CMP=0.
9.1.7
Status Register Protect (SRP1, SRP0)
The Status Register Protect bits (SRP1 and SRP0) are non-volatile read/write bits in the status register
(S8 and S7). The SRP bits control the method of write protection: software protection, hardware
protection, power supply lock-down or one time programmable (OTP) protection.

Notes:
1. When SRP1, SRP0 = (1, 0), a power-down, power-up cycle will change SRP1, SRP0 to (0, 0) state.
2. This feature is available upon special order. Please contact Winbond for details.
9.1.8
Erase/Program Suspend Status (SUS)
The Suspend Status bit is a read only bit in the status register (S15) that is set to 1 after executing a
Erase/Program Suspend (75h) instruction. The SUS status bit is cleared to 0 by Erase/Program Resume
(7Ah) instruction as well as a power-down, power-up cycle.
9.1.9
Security Register Lock Bits (LB3, LB2, LB1)
The Security Register Lock Bits (LB3, LB2, LB1) are non-volatile One Time Program (OTP) bits in Status
Register (S13, S12, S11) that provide the write protect control and status to the Security Registers. The
default state of LB[3:1] is 0, Security Registers are unlocked. LB[3:1] can be set to 1 individually using the
Write Status Register instruction. LB[3:1] are One Time Programmable (OTP), once it’s set to 1, the
corresponding 256-Byte Security Register will become read-only permanently.
