15.30 Non-volatile Protection Bit Program And Erase Flow
The device uses a standard command sequence for programming or erasing the Secured Silicon Sector
Protection, Password Locking, Persistent Sector Protection Mode Locking, or Persistent Protection Bits.
Unlike devices that have the Single High Voltage Sector Unprotect/Protect feature, the device has the
standard two-cycle unlock followed by 60h, which places the device into non-volatile bit program or erase
mode. Once the mode is entered, the specific non-volatile bit status is read on DQ0. Figure 15.1 on page 43
shows a typical flow for programming the non-volatile bit and Figure 15.2 on page 46 shows a typical flow for
erasing the non-volatile bits. The Secured Silicon Sector Protection, Password Locking, Persistent Sector
Protection Mode Locking bits are not erasable after they are programmed. However, the PPBs are both
erasable and programmable (depending upon device security).
Unlike Single High Voltage Sector Protect/Unprotect, the A6 pin no longer functions as the program/erase
selector nor the program/erase margin enable. Instead, this function is accomplished by issuing the specific
command for either program (68h) or erase (60h).
In asynchronous mode, the DQ6 toggle bit indicates whether the program or erase sequence is active. (In
synchronous mode, ADV# indicates the status.) If the DQ6 toggle bit toggles with either OE# or CE#, the non-
volatile bit program or erase operation is in progress. When DQ6 stops toggling, the value of the non-volatile
bit is available on DQ0.
