Programming Verification
SECURITY BITS
During the on-chip MTP ROM operation mode, the MTP ROM can be programmed and verified
repeatedly. Until the code inside the MTP ROM is confirmed OK, the code can be protected. The
protection of MTP ROM and those operations on it are described below.
The W77LE58 has several Special Setting Registers, including the Security Register and
Company/Device ID Registers, which can not be accessed in normal mode. These registers can only
be accessed from the MTP ROM operation mode. Those bits of the Security Registers can not be
changed once they have been programmed from high to low. They can only be reset through erase-
all operation. The contents of the Company ID and Device ID registers have been set in factory. Both
registers are addressed by the A0 address line during the same specific condition.
The Security Register is addressed in the MTP-ROM operation mode by address #0FFFFh.
B0
B1
B0: Lock bit, logic 0: active
B1: MOVC inhibit,
logic 0: the MOVC instruction in external memory
cannot access the code in internal memory.
logic1 : no restriction.
B2: Seed 0 & 1 access inhibit
B3: This bit must be H.
Default 1 for each bit.
